Hi everyone!
The following are the steps to load a excell sheet to oracle table.i tried to be as simple as possible.
thanks
Step # 1
Prapare a data file (excel sheet) that would be uploaded to oracle table.
"Save As" a excel sheet to ".csv" (comma seperated values) format.
Then save as to " .dat " file.
e.g datafile.bat
1,Category Wise Consumption Summary,Expected Receipts Report
2,Category Wise Receipts Summary,Forecast Detail Report
3,Current Stock List Category Wise,Forecast rule listing
4,Daily Production Report,Freight carrier listing
5,Daily Transactions Report,Inventory Value Report
Step # 2
Prapare a control file that define the data file to be loaded ,columns seperation value,name and type of the table columns to which data is to be loaded.The control file extension should be " .ctl " !
e.g i want to load the data into tasks table ,from the datafile.dat file and having controlfile.ctl control file.
SQL> desc tasks;
Name Null? Type
TASK_ID NOT NULL NUMBER(14)
TASK_NAME VARCHAR2(120)
TASK_CODE VARCHAR2(120)
: controlfile.ctl
LOAD DATA
INFILE 'e:\datafile.dat'
INTO TABLE tasks
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
(TASK_ID INTEGER EXTERNAL,
TASK_NAME CHAR,
TASK_CODE CHAR)
The above is the structure for a control file.
Step # 3
the final step is to give the sqlldr command to execute the process.
sqlldr userid=scott/tiger@abc control=e:\controlfile.ctl log=e:\logfile.log
