Conditional Mysql select statement

HI Folks
can anyone point me in the right direction with a MySQL statement.
I will try to layout my thinking here:
I have a form with three inputs area, name and search. I am trying to write a Mysql select statement that selects records from a single table if they match the criteria. Easy for two variables but I'm lost after that.
1. The form includes these three inputs:
area - drop down menu (Any as default)
name - drop down menu (Any as default)
search box - text area (Blank as default)
2. The form submits to itself leaving me with these three variables
$search=$_GET['search']
$area=$_GET['area']
$name=$_GET['area']
SELECT * FROM database WHERE database.description LIKE '%$search%' AND database.area LIKE '$area' AND database.name LIKE '$name'
3. This is where I get confused. How do I get the SQL to Select everything correctly. I have tried using PHP if/else code to fix it but I end up running around in circles with six different Select statements and haven't yet got that to work.
So I have come to the conclusion that there must be an easier way.  I see search forms with dozens of  search criteria on websites every day an d I only have 3 - so it can't be this complicated. Right?
I know I need to start from the beginning again but can anyone let me know how to approach it before I begin?
Cheers
Dave

Typically, I would build the where clause dynamically, based upon the values in your form. If the form field contains 'Any', leave it out of the where clause. So you can test each field value and either append or not to the end of the where clause.

  • MySQL Select Statement Help Required

    I am trying to generate a report in VS 2008 (C#) using a mysql select statement but cannot get it right.
    I have groups that meet on a weekly basis on different days. I want to generate a report that shows me all the members that have not attended their group where they have missed 3 meetings in a row.
    Below is the select statement I have tried but it does not give me the results I am looking for. I have tried to look at all the meetings in a 4 week period but would prefer to look at the last 3 meetings that are recorded. Some groups might not record a meeting every week. So I want to look at the last 3 recorded meetings and count each members attendance and only report on the members with more than 3 meetings missed.
    SELECT COUNT(`groupattendance`.`Attended`) AS Attendance, `smallgroupform`.`MeetingDate`, `userinfo`.`FirstName`, `userinfo`.`Surname`, `smallgroup`.`GroupName`, `groupattendance`.`Attended`, `groupattendance`.`UserID`, `groupattendance`.`GroupID`
    FROM ((`anatomy`.`groupattendance` `groupattendance`
    INNER JOIN `anatomy`.`smallgroupform` `smallgroupform` ON `groupattendance`.`FormID` = `smallgroupform`.`FormID`)
    INNER JOIN `anatomy`.`userinfo` `userinfo` ON `groupattendance`.`UserID` = `userinfo`.`UserID`)
    INNER JOIN `anatomy`.`smallgroup` `smallgroup` ON `groupattendance`.`GroupID` = `smallgroup`.`GroupID`
    WHERE (`smallgroupform`.`MeetingDate` >= DATE_SUB(CURDATE(),INTERVAL 4 WEEK) AND `smallgroupform`.`MeetingDate` <= CURDATE()) AND `groupattendance`.`Attended` = 'False'
    GROUP BY `userinfo`.`UserID`
    HAVING Attendance >= 3
    Thanks,
    Garth.

    Hi Garth,
    Seems no one can help you directly. Try googling your SQL request. Someone may be able to help you. At this point its not really a Cr problem.
    One option is to get all the data and add filtering using the record selection formula.
    Thank you

  • Concat java variable to a MySql select statement and exeucte

    Hi,
    I am trying to append a variable to a MySql select statement.
    Overview: I need to retrieve data from a MySql database with a java variable as a reference and select the data in the database based on that variable.
    CODE THAT I CURRENTLY HAVE:
    // Declare variables
    Connection conn = null;
    Statement st = null;
    Resultset rs2 = null;
    String st2 = null;
    String keyid = null;
    // Connect to database
    try {
          Class.forName("org.gjt.mm.mysql.Driver").newInstance();
          conn = DriverManager.getConnection("jdbc:mysql://" + mysql_host + ":3306/" + mysql_database, mysql_login, mysql_password);
          st = conn.createStatement();
          // Select data in Database with hanging equal sign
          st2 = ("SELECT * FROM table WHERE keyid= ");
          // Append keyid to hanging equal sign of select statement
          rs2 = st.executeQuery(st2 + keyid);
    }This is not working when I try to display the data.

    What is not working about it? Is there an error message? Stack Trace?
    Where do you get the value of keyId from?
    I would suggest that you use a prepared statement rather than building up a sql string like this. It prevents sql injection attacks
    // Declare variables
    Connection conn = null;
    PreparedStatement stmt = null;
    Resultset rs2 = null;
    String sql= null;
    String keyid = null;
    // Connect to database
    try {
          Class.forName("org.gjt.mm.mysql.Driver").newInstance();
          conn = DriverManager.getConnection("jdbc:mysql://" + mysql_host + ":3306/" + mysql_database, mysql_login, mysql_password);
          // Select data in Database with place holder for parameter
          sql = "SELECT * FROM table WHERE keyid= ?";
           // prepare the statement
          stmt = conn.prepareStatement(sql);
          // set the value of key id to use with the query
          stmt.setString(1, keyId);
          // run the query
          rs2 = st.executeQuery();
    catch (Exception e){
      System.out.println("An error occurred " + e.getMessage());
      e.printStackTrace();
    finally{
      if (rs2 != null) try { rs2.close(); } catch(SQLException ex){}
      if (stmt != null) try { stmt.close(); } catch(SQLException ex){}
      if (conn != null) try { con.close(); } catch(SQLException ex){}

  • Checking conditions in SELECT statement

    Hi All,
    I am relative new to ABAP and I would like to ask a question about checking conditions in SELECT statement in the "WHERE" part.
    There are two checkboxes at the selection screen and each should disable one of  conditions (marked with two stars) in the SELECT mentioned below.
    My question is, whether there exists an option how to solve this problem without using solution like:
    IF checkobx1.
    SELECT (without one condition)
    ELSEIF checkbox2.
    SELECT(without other condition).
    ELSE.
    SELECT (with both conditions)
      SELECT  qprueflos qherkunft qaufnr qsa_aufnr qmatnr qwerkvorg
              qpastrterm  qpaendterm
              qverid qobjnr vobjnr AS objnr_fa vauart

        ON qaufnr = vaufnr

    Hi,
    With this, I think u can directly read into WHERE clause
    IF checkbox1.
        v_where = '& BETWEEN ''&'' AND ''&'' '.
        REPLACE '&' WITH key_field INTO v_where.
        REPLACE '&' WITH field_LOW INTO v_where.
        REPLACE '&' WITH field_HIGH INTO v_where.
        CONDENSE v_where.
    ELSEIF  checkbox2.
        v_where = '& BETWEEN ''&'' AND ''&'' '.
        REPLACE '&' WITH key_field INTO v_where.
        REPLACE '&' WITH field_LOW INTO v_where.
        REPLACE '&' WITH field_HIGH INTO v_where.
        CONDENSE v_where.
    ENDIF.
    select * into corresponding fields of table ITAB
                 from (table_name)
                where (v_where).
    In this key_field is your fieldname in the where clause and field_low, field_high are range of values.
    If i write static query it looks like this
    RANGES: MATNR1 FOR MARA-MATNR.
      MATNR1-LOW = MATNR_LOW.
      MATNR1-HIGH = MATNR_HIGH.
      MATNR1-SIGN = 'I'.
      MATNR1-OPTION = 'BT'.
      APPEND MATNR1.
    select * into corresponding fields of table itab
    from mara where matnr BETWEEN 'M100' AND 'M200'.
    Hope it helps u

  • MySql select statement

    Hi All,
    I have java application which suppose to connect to MySql server and print the selected data.
    The application has 4 combo boxes (first item is empty): Name, Customer, Supplier, Status.
    User could choose any of these options. So there are huge number of select combinations.
    Is it possible to create one select statement template something like this:
    PreparedStatement stmt = con.prepareStatement( "SELECT * from database WHERE user_id = ?,
    and customer_id = ?,
    and supplier_id = ?,
    and status = ? " );
    if ( ! ComboBox.getSelectedItem().toString().isEmpty() )
    stmt00.setString( 1, ComboBox.getSelectedItem().toString() );
    else
    stmt00.setString( 1, "*" );
    etc…
    I'm stuck at this part stmt00.setString( 1, "*" ). Is there any way to write statement SELECT * from table WHERE column = * ?
    What is the proper way to write such selection ?
    Thanks in advance,
    Vladimir

    Is there any way to write statement SELECT * from table WHERE column = * ?No, that's invalid SQL.
    What is the proper way to write such selection ?If you need in one case to select a single user, but in another case to select all of them, then you need to handle two different SQL statements.
    1. SELECT * from table WHERE column = value
    2. SELECT * from table
    This has nothing to do with Java.

  • Please help - NE where condition in SELECT statement

    Dear experts,
    I am posting a section of my codes here for your review on performance tuning.
    In my second select statement, I used a "NE" where condition. I read somewhere in this forum that using "NE" where condition is not a good decision for improving codes' performance. What alternatives can I have to achieve the same purpose? May I use "NOT IN" here instead? Or do I use a LOOP for this (a rather manual way)?
    Just to let you all know that I still consider myself quite inexperienced in ABAP - please also let me know how I can better improvise my programming techniques in the posted codes here too.
    I will be most glad to provide you with further information if needed - just let me know.

  • Mysql select statement where = works and LIKE fails

    I am using Flash Builder 4. On the server side I use php and mysql. I created a php dataservice using FB4. My plan had been to allow users to enter a search term and query the database using a "LIKE" statement. FB4 created the php code that I simply modified changing the parameter name. The input parameter is a string.
    public function getT_caseByID($searchTerm) {
    $stmt = mysqli_prepare($this->connection, "SELECT * FROM $this->tablename WHERE (title = ?)");
    $this->throwExceptionOnError();
    mysqli_stmt_bind_param($stmt, 'i', $searchTerm);
    $this->throwExceptionOnError();
    mysqli_stmt_execute($stmt);
    $this->throwExceptionOnError();
    mysqli_stmt_bind_result($stmt, $row->idt_case, $row->title, $row->id_author, $row->comments);
    if(mysqli_stmt_fetch($stmt)) {
          return $row;
    } else {
          return null;
    A look at FB4 shows this code returns data.
    This code works fine but if I make the below change it fails, even when I use the wildcard %. the only change is "=" to "LIKE".
    public function getT_caseByID($searchTerm) {
    $stmt = mysqli_prepare($this->connection, "SELECT * FROM $this->tablename WHERE (title LIKE ?)");
    $this->throwExceptionOnError();
    mysqli_stmt_bind_param($stmt, 'i', $searchTerm);
    $this->throwExceptionOnError();
    mysqli_stmt_execute($stmt);
    $this->throwExceptionOnError();
    mysqli_stmt_bind_result($stmt, $row->idt_case, $row->title, $row->id_author, $row->comments);
    if(mysqli_stmt_fetch($stmt)) {
         return $row;
    } else {
         return null;
    A look into FB4 shows "void".
    Any help would be appreciated. I am using localhost on Apache Server on a development computer with Windows XP.

    Hi,
    1. Hit the Caps Lock key hard in your key board.
    2. Put your code between tags for better readability.
    3. When you have a where clause, why do you want to go for if clause? as in
    [code]
    update <your_table> set <your_col> = <your_new_val>
               where (select count(empid) from employee) > 1
    [/code]
    is logically equivalent to your
    [code]
    if (select count(empid) from employee) > 1 then
    update statement;
    end if;

    Why don't test simple cases like this first?
    An example to show it.

  • 1 Conditional report based on 3 select lists/ 3 different select statements

    I have made 1 report based on the three select lists. The report is displayed in the center of the page. The user needs to fill them in order, the select lists are:
    Selectlist:
    1. P1_LOVPG - Null is allowed, but is only appearing at top with a label of Productgroup
    2. P1_LOVSG - Null is allowed, but is only appearing at top with a label of Subgroup
    3. P1_LOVMA - Null is allowed, but is only appearing at top with a label of Manufacturer
    LOVPG contains a distinct collect of the ProductGroups
    QUERY LOV = select distinct pg from X
    LOVSG contains a distinct collect of the SubGroups inside the selected PG.list
    QUERY LOV = select distinct sg from X where pg = :P1_LOVPG
    LOVMA contains a distinct collect of the Manufacturers inside the selected SG.lst
    QUERY LOV = select distinct ma from X where sg = :P_LOVSG
    Based on the the selected items the user would see the following:
    Table X
    PG SG MA ART
    A-----X----M---1
    A-----X----N---2
    A-----Y----M---3
    A-----X----M---4
    B-----X----M---5
    B-----Y----N---6
    B-----Z----O---7
    Seletion 1 PG = A -> selects PG A in select list result, User sees:
    Report A
    PG SG MA ART
    A-----X----M---1
    A-----X----N---2
    A-----Y----M---3
    A-----X----M---4
    Query would be: select * from X where PG = :P1_LOVPG
    Selection 2, user still sees the above, can only select from the SG select list NULL, X, Y. User needs to choose between X or Y value. He picks X, he sees:
    Report B
    PG SG MA ART
    A-----X----M---1
    A-----X----N---2
    A-----X----M---4
    Query would be: select * from X where PG = :P1_LOVPG and SG = :P_LOVSG
    Selection 3, user still sees selection 2 on his screen, can only select from the MA list bewteen NULL, M or N, user needs to choose between M or N. He picks M, he sees:
    Report C
    PG SG MA ART
    A-----X----M---1
    A-----X----M---4
    Query would be: select * from X where PG = :P1_LOVPG and SG = :P_LOVSG
    As you can see the query changes as the user goes deeper into the structure. It is a simple if then else system where the quey changes. How do I set this up in htmldb?
    (I've read something about Oracle's SQL and it's decode function, but can they be used with changing select statements?)

    are you sure your data meets the JOIN conditions?
    You can make a quick check.. only example...
    select single * from KONP into ls_konp
    where knumh = P_knumh.
    if sy-subrc eq 0.
    select * from from A905 into table lt_a905 where
         kappl in so_kappl
         and kschl in so_kschl
         and VKORG in so_vkorg
         and vtweg in so_vtweg
         and kondm in so_kondm
         and wkreg in so_wkreg
         and knumh = ls_konp-knumh.
    if sy-subrc eq 0.
    select * from A919 into table lt_a919
    for all entries in lt_a905
    where kappl = lt_a905-kappl
    and kschl = lt_905-kschl
    and knumh = lt_905-knumh.
    endif.
    endif.

  • Field symbols as Table name and in where condition in a select statement

    Hello All,
    I have a scenario where I need to get user input on table name and old field value and new field value. Then based on user input, I need to select the record from the database. The column name for all the tables in question is different in the database, however there data type is the same and have same values.
    I am not able to use a field symbol for comparing the old field value to fetch the relevant record in my where clause.
    I cannnot loop through the entire table as it has 10 millilon records, please advice on how to add the where clause as field symbol as the table name is also dynamically assigned.
    Here is my code:
    DATA: TAB       LIKE SY-TNAME,
          TAB_COMP1 LIKE X031L-FIELDNAME,
          TAB_COMP2 LIKE X031L-FIELDNAME,
          NO_OF_FLD TYPE N.
    DATA: BEGIN OF BUFFER,
            ALIGNMENT TYPE F,
            C(8000)   TYPE C,
          END OF BUFFER.
    FIELD-SYMBOLS: <WA>   TYPE ANY,
                  <COMP1> TYPE ANY,
                  <COMP2> TYPE ANY.
    GET TABLE NAME GIVEN BY USER IN LOCAL VARIABLE
      TAB = TAB_NAME.
    CREATE FIELD NAME BASED ON THE TABLE NAME ENTERED.
      CASE TAB_NAME.
      WHEN 'OIUH_RV_GL'.
          KEY FIELD
            TAB_COMP1  = 'GL_GL_SYS_NO'.
            NO_OF_FLD  = 1.
      WHEN 'OIUH_RV_OPSL'.
          KEY FIELD
            TAB_COMP1  = 'OPSL_GL_SYS_NO'.
            NO_OF_FLD  = 1.
      WHEN 'OIUH_RV_OTAX'.
          NOT THE ONLY KEY FIELD
            TAB_COMP1  = 'OTAX_GL_SYS_NO'.
            TAB_COMP2  = 'OTAX_TAX_POS_NO'.
            NO_OF_FLD  = 2.
      WHEN 'OIUH_RV_GTAX'.
          NOT THE ONLY KEY FIELD
            TAB_COMP1  = 'GTAX_GL_SYS_NO'.
            TAB_COMP2  = 'GTAX_TAX_POS_NO'.
            NO_OF_FLD  = 2.
      WHEN OTHERS.
            EXIT.
      ENDCASE.
    SET FIELD SYMBOL WITH APPROPRIATE TYPE TO BUFFER AREA.
    ASSIGN BUFFER TO <WA> CASTING TYPE (TAB).
    How to add where clause and remove the if condition in the select -- endselect
    SELECT * FROM (TAB) INTO <WA>. 
      ASSIGN COMPONENT TAB_COMP1 OF STRUCTURE <WA> TO <COMP1>.
      IF NO_OF_FLD = 2.
        ASSIGN COMPONENT TAB_COMP2 OF STRUCTURE <WA> TO <COMP2>.
      ENDIF.
      IF <COMP1> = OLD_SYS_NO.
        code for updating table would come here
          WRITE: 'MATCH FOUND'.
          EXIT.
      ENDIF.
    ENDSELECT.
    Please advice. Thanks much.

    1. Create single column table for holding field name depending on the table entered.
    2. Take input from user: for e.g. table_name
    3. Using case load single column table with required fields
       for e.g.
      CASE TAB_NAME.
       WHEN 'OIUH_RV_GL'.
             Append 'GL_GL_SYS_NO' to KEY_FIELD --> KEY_FIELD is the single line internal table as mentioned in step 1.
       WHEN 'OIUH_RV_OPSL'.
             Append 'OPSL_GL_SYS_NO'.
       WHEN 'OIUH_RV_OTAX'.
             Append 'OTAX_GL_SYS_NO' to KEY_FIELD.
               APPEND 'OTAX_TAX_POS_NO' to KEY_FIELD.
       WHEN 'OIUH_RV_GTAX'.
             Append 'GTAX_GL_SYS_NO' to KEY_FIELD.
               APPEND 'OTAX_TAX_POS_NO' to KEY_FIELD.
       WHEN OTHERS.
          EXIT.
       ENDCASE.
       Now depending on the table name you have required column ready
    4. Create dynamic internal table using following sudo code
       Fill the fieldcatlog using the single column field table and DD03L table, See what all columns from DD03L you want to fill in field catlog table
       loop at internal table with all the fields.
        move it to field catalog.
        append field catalog.
       endloop.
    5. Pass this field catalog table to static method create_dynamic_table method
       DATA table TYPE REF TO DATA. --> data object for holding handle to dynamic internal table.
       call method cl_alv_table_create=>create_dynamic_table
       exporting
          it_fieldcatalog = fieldcatalog_tab
       importing
          ep_table = table.
    6. Now assign table reference to field symbol of type table.
       ASSIGN table->* to <field-tab>.
    7. Also create work area <field-wa> using refrence of table.
       create data object wa LIKE LINE OF <field-tab>.
       ASSIGN wa->* to <field-wa>.
    8. Also define field symbol for field name.
       for e.g. <field_name>
    4. Dynamic internal table is ready
    5. Now execute the select statement as follows:
       SELECT (KEY_FIELD)
         INTO <ITAB> --> created dynamically above
          FROM (TABLE_NAME)
         WHERE (WHERE).  --> WHERE is single line internal table having line type of CHAR72. So for every old value there will be one line
         Where condition is same as like we give in static way only difference in this case it will stored in internal table line wise.
        In this case you need to append all your where condition line by line in to WHERE.     
    5. To fill this dynamic internal table using ASSIGN COMPONENT <Comp_number> OF STRUCTURE <field-wa> TO <field-name>
       So in this case if first field of structure STRUCT1 is user_id then sudo-code will be
       loop at internal table containing list of fields into field_wa --> single column field table
           ASSIGN COMPONENT field_wa OF STRUCTURE <field-wa> TO <field>. "Here field_wa is wa area for single column internal table holding all the fieldnames.
           Now <field-name> points to user_id field. Move some value into it as nornally we do with variables.
           Move <your_new_value> to <field-name>. --> Assign new value
            or
            <field-name> = <your_new_value>.
       Endloop.
    6. After completing all the fields one row will be ready in <field_wa>.
       APPEND <field_wa> to <field_tab>.
    Hope this helps you.
    Thanks,
    Augustin.
