Sql Problems, Same Field Names In Multiple Mysql Tables?

I have a keyword search that searches multiple DB tables for thumbnail images using UNION ALL. I have two pages, results.php, and view.php. My goal is to able to click a thumbnail image on results.php and be directed to a larger version of that same image on view.php. The problem is each image in all my tables uses the field name "id" so when I click a thumbnail on results.php I get two different images with the same id from different tables. I tried changing the id's to different names, but when it was time to pass url parameters I can only choose 1 value. (if you can choose more than 1 I don't know how). So my question is why are my id's from different tables being grouped together, and how can I change this?
Image Results Page (which works perfect):
SELECT *
FROM table1
WHERE keyword LIKE %colname% OR id LIKE %colname%
UNION ALL
SELECT *
FROM table2
WHERE keyword LIKE %colname% OR id LIKE %colname%
View Image Page (having problems here):
SELECT *
FROM table1
WHERE id = colname
UNION ALL
FROM table2
WHERE id = colname

Yes, that is going to be a problem - and it's just the beginning of your problems when you do not normalize your data. Your data model is not correct. You should not be storing similar data in 15 tables - it's a really big mistake.
To solve your current problem you would need to include a table identifier in the query results in the Image results page, and pass that to the view page and then use PHP to dynamically create the SQL with the correct table....ugh!

Finding same column name from multiple database tables

I am needing to find all tables in a database that contain the same column. ie: which tables in database A have col_a in it.
Is it possible to do a sql code to qry all of this?
Thanks

No, Ignacio did not, at least, not really. ;)
The usage of ALL_TAB_COLUMNS only has info for tables which the actual user has access to.
If you need to be sure that you search each and every table, you have to use DBA_TAB_COLUMNS (or the connected user must be a super hero...).
Just wanted to point that out.

CFUPDATE problem with field name beginning with a number

I have a form (actually several) that is gathering data for a survey. I tried to use cfupdate to update the data elements and got a string index out of range error. I tested again without the form fields that began with numbers and it worked just fine. I then tried to enclose the offending field names in () and []. Both times I got same error. Does anyone have a work around for this? The code and error are below.
Changing the field names is not really an option. This survey has almost 400 data points and most of the fields begin with the question number.
Thanks

I think you have run one of CFUPDATE's limitations. I am not 100% certain, but I do not think cfupdate provides a way to escape invalid column names like yours. In which case you may need to do a regular UPDATE within a cfquery instead... or rename your columns.
fields that began with numbers
Most databases discourage creating column names that start with a number (or other restricted characters). While many databases will allow you to escape invalid names, it is simpler all around to avoid them altogether. Otherwise, you may have to escape the names in every single query. The recommendations vary, but usually object names that begin with a letter, and contain only letters, numbers and underscores are considered safe.
This survey has almost 400 data points and most of the fields begin with the question number.
Four-hundred (400) is a lot of columns for a single table. The fact that they all them seem to contain the same type of information (ie response to a question) is an indication that data should probably be stored in a separate table, as rows, not columns. For example questions could be stored in one table, possible answers in another, and the results of an individual test/survey stored in a third table. A structure like that is much easier to query, can easily accommodate changes (add/remove questions, responses, etcetera) without having modify the table every time.

XML Parsing issue with same tag names at multiple levels.

My XML has the same tag name , ID at different levels in the XML.
<InventorySearch>
<*ID*>ID1</*ID*>
<interactionDate>2012-09-01T10:30:00Z</interactionDate>
<DescribedBy>
<value>Cycle Count extract</value>
<Characteristic>
<*ID*>ID2</*ID*>
</Characteristic>
</DescribedBy>
<type>Cycle Count</type>
<InventorySearchComprisedOf>
<*ID*>ID3</*ID*>
<quantity>
<amount>1</amount>
<units>EACH</units>
</quantity>
<itemDateComplete>2012-09-07T10:30:00Z</itemDateComplete>
<itemStatus>Open</itemStatus>
</InventorySearchComprisedOf>
</InventorySearch>
When I use the Extract function with XML Sequence, I am getting all the ID values concatenated.
select extract(value(d),'//ID/text()').getstringval() as id1,
extract(value(e),'//ID/text()'). getstringval() as id2
from xxnbn_cc_response_xml_stg x,
table(xmlsequence(extract(x.xml_column,'/InventorySearch'))) d,
table(XMLSEQUENCE(extract(D.column_value,'//InventorySearchComprisedOf')))(+) E;
Return values :
ID1 - ID1ID2ID3
ID2 - ID3
Is this the right way to parse this type of XML?

The answer would depend upon your version of Oracle
select * from v$version
and the desired result set you want to see.
If you are 10.2 or later, than XMLTable would be easier to write, but I won't go that way until we know more about what you want to see.

Problem getting field names with OCI

Hi,
I am trying to retrieve the names of select fields through the

Has anyone else seen this before, and if so, how do you get
around it? Let me know if you need more details.

Searching multiple mysql tables, Joins?

I'm creating a mysql keyword search on my website and I know how to search a single mysql table, my problem is I need to search 15 different tables simultaneously, they also all have the same column names. I was told I have to you JOINS but i've never used them before. How is this done?
MY SQL SELECT:
SELECT *
FROM mytable1
WHERE keyword LIKE %colname% OR id LIKE %colname%

OK, that really doesn't answer my question. Just because they are in different categories is not a valid reason. Why can't they be mixed?
In any case, you could probably use a UNION query to solve the current problem, but I would have to know more about the complete query. You don't want to use a JOIN.

Get Table fields name for an SAP table

hi,
i need to pass SAP table name as a parameter to the selection screen of a Report program.
This prog shud give me the table Fields name along with type and length.
Is there any standard SAP report program for the same or i have to write my own logic?
Please advise.
regards,
ags.

Hi,
For your requirement you have to write own program in dynamic manner by using field symbol concept.
Use this FM DDIF_FIELDINFO_GET and get the field information of database table.
call function 'DDIF_FIELDINFO_GET'
    exporting
      tabname        = <master>    u201C Table name
    Tables
      DFIES_TAB      = <table_field> u201C here you will get field information of table
    exceptions
      not_found      = 1
      internal_error = 2
      others         = 3.
if sy-subrc <> 0.
    message text-005 type 'E' .
endif.
Loop <table_field> assignigng <field>
*---here you have to collect the relevant information that you are going to display in your output.
Endloop.
Use any one of ALV or OOALV and display your records.

How can i read the field name in the internal table

Hi friends
i want to read the internal table filed name.
my requirement is like this:
data: begin of t_header occurs 0,
       extno(12),
       priotiy(5),
       ecnumber(10).
      end of t_header.
loop at t_header.
if the field name is priority i want to write some other
logic here.....
endloop.
Please tell me how can i do this.

data: wf_fld_cat type slis_t_fieldcat_alv .
data: wf_repid like sy-repid .
data: int_tab_name type slis_tabname .
move: sy-repid to wf_repid ,
        'INT_OUTPUT' to int_tab_name .
call function 'REUSE_ALV_FIELDCATALOG_MERGE'

How to get field name dynamically of a table

Hi,
I have a table which has 5 fields, now i want to know the name of the fields dynamically at run time
not the values each fields hold.
I have tried field symbols, get reference but all i got the value of the field not the field name.
is there any way i can get the field name.
regards,
mayank

1. If it is a DDIC table, you can use the FM 'DDIF_FIELDINFO_GET'. Search in SDN for details.
2. If it is an internal table, check this code:
TYPE-POOLS: abap.
PARAMETERS p_table TYPE tabname .
DATA: lcl_table TYPE REF TO cl_abap_tabledescr,
      lcl_struc TYPE REF TO cl_abap_structdescr,
      it_fields TYPE abap_compdescr_tab,
      wa_fields TYPE abap_compdescr.
DATA: dref TYPE REF TO data.
FIELD-SYMBOLS: <itab> TYPE ANY.
CREATE DATA dref TYPE STANDARD TABLE OF (p_table).
ASSIGN dref->* TO <itab>.
START-OF-SELECTION.
* Get the Table details
lcl_table ?= cl_abap_typedescr=>describe_by_data( <itab> ).
* Get the table line type i.e., structure details
lcl_struc ?= lcl_table->get_table_line_type( ).
* Get the components(fields) of the table line
it_fields = lcl_struc->components.
LOOP AT it_fields INTO wa_fields.
    WRITE: / wa_fields-name.
ENDLOOP.

Debugging ECC6: how to see the fields name when download internal table?

When we debug a reprot in ECC6 and save to a local file an internal table, the fields are not appearing only the data,
Is there a way to download also the table fields name?

From the new debugger switch to the classic debugger using menu path Debugger->Switch to Classic Debugger. Form the classic debugger you can download internal table data with column name(s).

In FTP server same file name with multiple vesions

Hi All,
My source system is UNIX. in that FTP server they have multiple files with same name example " abc.dat"; with different versions example"abc.dat;43" "abc.dat;44", "abc.dat;45". . so how to read latest version file like "abc.dat;45"   from sender communication channel with file adapter.
suggestions please..Thanks in advance.
Edited by: venkataraonandigam on Jul 15, 2011 3:12 PM

Hi VenkatRao,
Sender file adapter configuration has an option "Processing Sequence". In the that select by"Date" or Name .
If you used placeholders when specifying the file name, define the processing sequence of the files:
○       By Name: Files are processed alphabetically by file name.
○       By Date: Files are processed according to their time stamp in the file system, starting with the oldest file.
Otherwise you have to write shellscrit to move the latest version file to a different folder and pick it up from that folder.
Or
write adapter module.
