Applies to: SQL Server (all supported versions) Azure SQL Database Azure SQL Managed Instance Azure Synapse Analytics Parallel Data Warehouse
By default, the Query and View Designer joins tables using an equal sign (an equijoin), which matches values in the two join columns. If you want, you can change the operator used to compare values in the join columns.
To modify join operators
In the Diagram pane, right-click the join line you want to modify, and then choose Properties from the shortcut menu.
In the Property window, click Join Condition and Type and click the ellipses (...) to the right of the property.
In the Join dialog box, select a new operator.
