Hello all !!!!
I have problems with assignment of value of an input variable to temporary variable. I create service with SQL Query. Added an input variable [[container]] with type of data a string. In assignment attempt: set @Container=[[container]] - the compiler ceases to highlight syntax and execution happens to an error. At execution of any command as soon as I insert an input variable, [[.....]] check of syntax shows that it is not right.
Whether somebody knows in what an error? In SQL Managment studio everything works.
My best guess is that the compiler within composer isn't set up to recognize that syntax as a possible parameter substitution.
You can try the more dangerous and more powerful << >> which is a string substitution and shouldn't cause any complaints but exposes you to potential SQL Injection
You suggest to write set @container=<<container>>; instead of
set @container=[[Container]] ?
For input parameters into a service standard when you bring it in it will be [[ ]] which is Parameter substitution but << >> is String substitution, so potentially the service is more 'forgiving'
If it still doesn't accept that, then you may have to go the full 'build your query as a string' route and then execute it with <<YourFullSQLStringHere>> approach
Here is an article on it: https://community.ptc.com/t5/ThingWorx-Developers/How-can-I-execute-a-sql-query-constructed-dynamica...
I tried to do so
IF <<Container>> is not nullThe compiler returned the message "Unable to Invoke Service GetEquipment MSSQL : null"
<<IF [[Container]] is not null>>The compiler returned the message"Unable to Invoke Service GetEquipment on MSSQL : Execute Query failed: com.microsoft.sqlserver.jdbc.SQLServerException: Incorrect syntax near '<'."
Did you try
and then supply that full string as an input parameter to your SQL Query/Command
and then do <<MyInputParameterSQLString>>
