Create a stored procedure to upload data from 3 csv files one after other.

Name of the csv file(s) already saved in a table myFileList.

myFileList Table contains values like crashData_MMYYYY_vN.csv, vehecleData_MMYYYY_vN.csv, casualtyData_MMYYYY_vN.csv etc with different versions and MMYYYY values.

Example: For January month, MM should be 01. For October, it should be 10.

For Base version value of ‘N’ should be 1 and can be incremental for the next versions, viz., v2, v3 etc.

The first version of a crash file loading for Jan 2013 should be named ‘crashData_012013_v1’.


  1. If crashData_012013_v2 is available no need to consider crashData_012013_v1 ( Same case for 'vehecleData_MMYYYY_vN.csv' and 'casualtyData_MMYYYY_vN.csv')

  2. If any of the file(s) is missing no need to insert any data into the table.

  3. i need to ensure that only the last 1 calendar month’s data is uploaded.

Thanks in advance.

Looks like a homework question to me.

if(filename==x) call procedure1 else if (filename==y) call procedure2 else call procedure3

Note :filename is stored in a table. How to do this?

Is there a theoretical maximum value for N?

Dec 12, 2012 at 09:25 AM ThomasRushton ♦♦

Nope.. Where i am stuck is if(filename==x) call procedure1 else if (filename==y) call procedure2 else call procedure3

1 answer: sort voted first

If you're just having problems with the `IF` clause...

Try something like:

 IF Condition1
     EXEC Proc1
     IF Condition2
         EXEC Proc2
         EXEC Proc3

Note that, because I've only put one statement in the THEN/ELSE parts, the BEGIN/END bits are unnecessary. I've left them in through force of habit - the number of times I've not written them and had something a bit odd happen...
