dbQueryFetchAllSA

Purpose

Returns the result set for the current query as a string array.

Format

result = dbQueryFetchAllSA(qid[, columns])
Parameters:
  • qid (scalar) – query number.

  • columns (string or string array) – Optional input. Gives specific columns to pull out from result matrix. Must be a subset of fields from SELECT statement.

Returns:

result (string array) – containing the result set for the current query. If the result set is empty, a scalar error code is returned.

Examples

// Prepare a query
qid = dbExecQuery(db_id, "SELECT * FROM
     PEOPLE WHERE COUNTRY = ?", "USA");

/*
** Specify 'FIRST_NAME' and 'LAST_NAME'
** as columns of interest
*/
names = dbQueryFetchAllSA(qid,
     "FIRST_NAME"$|"LAST_NAME");

/*
** Print result if 'names'
** is not a scalar error code
*/
if not scalmiss(names);
    print "People in the USA = " names;
endif;

Remarks

For numerical only results, use dbQueryFetchAllM() to return a matrix.

This function retrieves all rows at once. You can process rows in an iterative manner by using dbQuerySeekNext() with either dbQueryFetchOneM() or dbQueryFetchOneSA().
