I want to get the database value to environment variable and assign to a local variable so that i could do some manipulations on it and store it back to the database. I am doing something like this
SET Environment.Variables.DBDATA[] = SELECT d.GMT FROM Database.dbo.GMT_EST as d;
SET DB_TS = Environment.Variables.DBDATA[1].Field1;
But DB_TS always contain null. Please help. I am totally new to MB with very less training.  |

Ask your manager / team leader to provide you some formal education. Alternatively you can read the infocentre. This IS NOT a training forum. |

The output of a USERTRACE with it set to output ${Environment} would also help.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

Please don't discourage if you can't help.
Used this and it worked. DBDATA[1]..GMT instead of DBDATA[1].Field 1
SET DB_TS = CAST(Environment.Variables.DBDATA[1].GMT AS CHARACTER); |

Quite the opposite. I am encouraging you to get formal training or use the infocentre. There are several samples provided with the product, you can follow the instructions supplied and go through them and learn. |

Welcome to WMB/IIB. A couple of tips to help you with developing message flows:
- The debugger is great for finding many problems
- ...but sometimes you will need to use Trace nodes and user trace to diagnose a problem.
A Trace node shows you *exactly* what the message tree looks like at a particular point in your message flow.
A user trace is a detailed execution trace, and it is designed to help with problem diagnosis. Use the commands mqsichangetrace, mqsireadlog and mqsiformatlog ( in that order ) to take a user trace. You can search for 'mqsichangetrace' in this forum to find actual examples of those commands.
