SQL Query

The information on this page relates to the new upgraded interface of the IConduct platform. To view information about the Classic version of the user interface, follow this link.

 

The SQL Query algorithm allows you to manipulate data in an existing schema using specific SQL syntax. You can examine the expression prior to running it.

 

An SQL Query step allows you to select, insert, update and/or delete data from the Schema using any valid SQL syntax. The results of the step will completely replace the previous data stored in the Schema. This means that if you want to insert a row into the current Schema, you first need to define an Insert statement, and then define another Select statement on the entire Schema table.

 

The SQL expression must contain a Select statement.

Remember to map the query results to the Schema columns, otherwise you will not see anything in the Schema.

 

The Manipulate Schema Step: SQL Query page is illustrated in the figure below (note the presence of a Select statement):
