If the array variable has not been used before calling <b>maxdb_stmt_bind_param()</b>, it has to be initialized as an emtpy array. See the examples how to use <b>maxdb_stmt_bind_param()</b> with extended syntax. </p> <p class="para"> Variables for SELECT INTO SQL statements can also be bound using <b>maxdb_stmt_bind_param()</b>. Parameters for database procedures can be bound using <b>maxdb_stmt_bind_param()</b>. See the examples how to use <b>maxdb_stmt_bind_param()</b> in this cases. </p> <p class="para"> If a variable bound as INTO variable to a SQL statement was used before, the content of this variable is overwritten by the data of the SELECT INTO statement. A reference to this variable will be invalid after a call to <b>maxdb_stmt_bind_param()</b>.⌨️ 快捷键说明
