Hello,
I have software compiled in Oracle 9 environment. And when I try to fetch data using
different versions of Oracle client/server I receive ORA-errors:
1. client 9 --> server 8: "ORA-00932: inconsistent datatypes"
2. client 8 --> server 9: "ORA-01455: converting column overflows integer datatype"
These errors do not occur when connecting client 9 to server 9.
I use the following example code (similar to example in Oracle 9 documentation):
EXEC SQL BEGIN DECLARE SECTION;
int intn_b;
VARCHAR buffer[6];
VARCHAR cursor_def[500];
EXEC SQL END DECLARE SECTION;
strcpy((char*)cursor_def.arr, "SELECT tstintn,tstcode FROM test WHERE tstcode LIKE 'AU%'");
cursor_def.len = strlen((char*)cursor_def.arr);
EXEC SQL PREPARE S FROM :cursor_def;
EXEC SQL DECLARE My_cursor CURSOR FOR S;
EXEC SQL OPEN My_cursor ;
EXEC SQL WHENEVER NOT FOUND DO break;
for (;;)
{
int i=0;
EXEC SQL FETCH My_cursor INTO :intn_b, :buffer;
buffer.arr[buffer.len] = '\0';
printf("%6d %7s\n", intn_b, buffer.arr);
}
EXEC SQL CLOSE My_cursor;
When I declare cursor without using dynamic SQL:
EXEC SQL DECLARE My_cursor CURSOR FOR
SELECT tstintn, tstcode FROM test WHERE tstcode LIKE 'AU%';
everything works fine.
Does anyone know how to solve this problem?
