<title>Description</title>
<para>This function returns a result set row to the calling procedure's context, whether it is
the client, exec function or a procedure view). The row's values are the elements of the supplied
res_values_array vector.</para>
</refsect1>
<refsect1 id="params_exec_result"><title>Parameters</title>
<refsect2><title>res_values_array</title>
<para>This parameter can be one of two things:</para>
<simplelist>
<member>a vector of strings (like vector('cola', 'colbb')).
When used that way it makes columns named 'cola' and 'colb' with type ANY and
precision 256</member>
<member>an array with the same format as the 0th element of the metadata
returned by <function>exec()</function> and <function>rexec()</function>,
which contains all the type information and can be used directly.</member>
</simplelist></refsect2>
</refsect1>
<refsect1 id="ret_exec_result"><title>Return Types</title>
<para>The row's values are the elements of the supplied
res_values_array vector. For example:
<computeroutput>exec_result (vector (1, 'a'))</computeroutput> will return a row of two columns:
1 and 'a'. This is similar to the <function>result()</function> function, but it uses an array instead of
parameter list</para>
