| Specification: | DB2 CLI 1.1 | ODBC 1.0 | ISO CLI |
SQLRowCount() returns the number of rows in a table that were affected by an UPDATE, INSERT, DELETE, or SELECT with scrollable cursor statement executed against the table.
SQLExecute() or SQLExecDirect() must be called before calling this function.
Syntax
SQLRETURN SQLRowCount (SQLHSTMT StatementHandle, /* hstmt */
SQLINTEGER FAR *RowCountPtr); /* pcrow */
Function arguments
Table 78. SQLRowCount arguments
| Data type | Argument | Use | Description |
|---|---|---|---|
| SQLHSTMT | StatementHandle | input | Statement handle. |
| SQLINTEGER | RowCountPtr | output | Pointer to location where the number of rows affected is stored. |
Usage
If the last executed statement referenced by the input statement handle is not an UPDATE, INSERT, or DELETE statement, or if it did not execute successfully, then the function sets the contents of RowCountPtr to -1.
Any rows in other tables that might have been affected by the statement are not included in the count.

It is likely that process-level memory has been exhausted for the application process. Consult the operating system configuration for information on process-level memory limitations. |
| HY010 | Function sequence error. | The function is called prior to calling SQLExecute() or SQLExecDirect() for the StatementHandle. |
| HY013 | Unexpected memory handling error. | DB2 CLI was unable to access memory required to support execution or completion of the function. |
