Results-handling for language commands

Code your application to handle the results of a language command with a standard results loop, as discussed in “Structure of the basic loop”.

Language commands can return the result types listed in Table 5-2, for the given reasons:

**Table 5-2: Result types from the execution of a language command**
Result type	Meaning/when received
CS_ROW_RESULT	Regular rows, sent in response to a select statement executed by the language batch or by a called stored procedure.
CS_COMPUTE_RESULT	Compute rows, sent in response to a selectstatement that contains a compute clause. The select statement can be executed by the language batch or by a called stored procedure.
CS_PARAM_RESULT	Output parameter values, sent in response to an exec statement that passes parameter values. (Parameters must be qualified with output in the exec statement.) Output parameter values are received after the results of all statements executed by the procedure.
CS_STATUS_RESULT	A stored procedure’s return status, sent in response to an exec statement. The return status is received after the results from all statements executed by the procedure.
CS_COMPUTEFMT_ RESULT, CS_ROWFMT_RESULT	Format results, seen only if the CS_EXPOSE_FMTS connection property is CS_TRUE (the default is CS_FALSE).
CS_CURSOR_ RESULT	Cursor result rows are retrievable using ct_fetch or ct_scroll_fetch.
CS_CMD_DONE	Placeholder to indicate that the results of one logical command have been processed. Seen after the following events: The results from each statement executed in the language batch have been processed. The results of each select statement executed by a called stored procedure have been completely processed.
CS_CMD_SUCCEED	Indicates the success of an insert, update, or exec statement that was executed directly by the language batch.
CS_CMD_FAIL	Indicates that the command or a statement within the language batch failed to execute.
