Re: SQLSTT Error Code 01003

This is a document I wrote up on nulls, RPG and SQL. Hope it is helpful.

Using Nulls In RPG and SQL



If you have a table that supports nulls, you either need to read the record
in RPG and see if fields in the table are null or set the null condition
when you insert the record



The trick is not to put a comma between the list of variables. SQL
Pre-Compiler sees this and says this must be an indicator array.



In this example, I am using named indicators rather than NullInd(1), etc.
NullInd is mapped to dsNullInd so dsNullInd and the array NullInd are the
same thing.



Note that because I am using qualified data structures I can use the same
name for the null fields as the record fields.



d cSqlNotNullIndicator…

d c Const(0)

d cSqlNullIndicator...

d c Const(-1)



d dsRecord...

d ds Qualified

d CustName...

d Like(StdNam)

d CustLibrary...

d Like(StdNam)



d dsNullInd...

d ds Qualified

d CustName...

d 5i 0

d Inz(cSqlNotNullIndicator)

d CustLibrary...

d 5i 0

d Inz(cSqlNotNullIndicator)



d ptrNullInd...

d s Like(StdPtr)

d Inz(%Addr(dsNullInd))



d NullInd...

d s 5i 0

d Dim(2)

d Based(ptrNullInd)



Exec Sql Select Field1,

Field2

Into :dsRecord :NullInd

From FileY;



If dsNullInd.CustName = cNullIndicator; // If null in database.

// Do something

EndIf;



Or



Exec Sql Fetch From C1

Into :dsRecord :NullInd;



If dsNullInd.CustLibrary = cNotNullIndicator; // If not null.

// Do Something

EndIf



Or



Exec Sql Update FileY

Set(CustName = :CustName :NullInd)



Or



dsNullInd.CustName = cNullIndicator;



Exec Sql Insert Into FileY

Values(:dsRecord :NullInd);



RPG ends up looking like:



//****ec Sql Insert Into FileY

//**** Values(:dsRecordOut :NullInd);




C EVAL SQL_00005 = DSRECORD.CUSTNAME


C EVAL SQL_00006 = DSRECORD.CUSTLIBARY

C EVAL SQL_00007 = NULLIND(1)

C EVAL SQL_00008 = NULLIND(2)

Subject: SQLSTT Error Code 01003

I am trying to figure out what this error means beyond "01003 - Null

values

removed from column function argument(s)." It is causing issues in my
program. I check to be sure that SQLSTT is 0 or 2000. This is the first
time
I have come across this error and the error message isn't very helpful
here.
