getCol

syntax

 mixed getCol {
       mixed $sql
       optional string[] $bindvars
       optional bool $trimString
       }

Description

The function executes a statement and returns the first column of each row of the the entire recordset in an array or false if the statement execution fails. If no records match the provided SQL statement, an empty array is returned.

The presentation of the returned data can be modified by:

$ADODB_FETCH_MODE variable,
ADODB_ASSOC_CASE constant,
setFetchMode() function.

For a detailed description of the SQL and bind parameters passed, see execute().

The optional third parameter passed enables space trimming of the returned value. This is only relevant if the returned string is coming from a CHAR type field.

 * $ar returns:
