The property value as LONG VARCHAR.

If the message property value is out of range, then a SQL error with SQLSTATE 22003 occurs.

You can read this property after a message is received and until a rollback or commit occurs; after that you cannot read it.

• ml_qa_setstringproperty
• ml_qa_createmessage
• ml_qa_getmessage
• Custom message properties

In the following example, a message is received and the value of the string property mystringproperty is output to the database server messages window:

begin
    declare @msgid varchar(128);
    declare @prop long varchar;
    set @msgid = ml_qa_getmessage( 'myaddress' );
    set @prop = ml_qa_getstringproperty( @msgid, 'mystringproperty' );
    message 'message property mystringproperty is set to ' || @prop;
    commit;
end
