Can/Should we check for error on connection object after the followng calls

Normally after a call to the 'SQLDBC_Connection_connect' function we check for the possible errors by calling the

SQLDBC_ErrorHndl *errHndl = SQLDBC_Connection_getError(conn);

SQLDBC_ErrorHndl_getErrorText(errHndl); or SQLDBC_ErrorHndl_getErrorText(errHndl);

Should we be doing the same after the following calls too ? They all take 'SQLDBC_Connection*' as a parameter just like 'SQLDBC_Connection_connect' . In other words the question is is the SQLDBC_Connection object set with the error information (if any) in case any of the following call fails?







Please advise.

Hello Raj

Usually checking the error is sensible, if the method in question returns a value of type SQLDBC_Retcode.

However, createStatement sets a memory allocation error, if no statement could be generated due to memory restrictions and therefore a NULL would be returned.
