![]() ![]() To populate an empty string, use the following expression: %""%. PSEQUEL QUERY HOW TOYou can find more information about UI automation and how to use the respective actions in Automate desktop flows.Īfter selecting Encrypt with Password, populate an empty string in the popup dialog using the Populate text field in windows action. Next, deploy the appropriate UI automation actions and navigate to File > Info > Protect Workbook > Encrypt with Password. PSEQUEL QUERY PASSWORDThe file is password-protected, so populate the appropriate password in the Password field. To achieve that, launch the Excel file using the Launch Excel action. The Open SQL connection action can't connect to password-protected Excel files, so you have to remove the protection. Open an SQL connection to a password-protected Excel fileĪ different approach is required in scenarios where you run SQL queries on password-protected Excel files. PSEQUEL QUERY INSTALLTo use the presented connection string successfully, you have to download and install Microsoft Access Database Engine 2010 Redistributable. ![]() Provider=.12.0 Data Source=%Excel_File_Path% Extended Properties="Excel 12.0 Xml HDR=YES" Now, deploy the Open SQL connection action and populate the following connection string in its properties. Optionally, you can skip this step and use the hardcoded path of the file later in the flow. ![]() To establish the connection, create a new variable named %Excel_File_Path% and initialize it with the Excel file path. Open an SQL connection to an Excel fileīefore running an SQL query, you have to open a connection with the Excel file you want to access. Oppositely, you can implement this functionality with SQL queries using only two actions, the Open SQL connection action and the Execute SQL statements action. To achieve this functionality without SQL queries, you need loops, conditionals, and multiple Excel actions. Suppose a flow has to modify only the Excel registries that contain a particular value. Instead of looking for a tool that will allow us to rollback our DB changes automatically, we decided to implement backwards-compatible DB changes, for example adding a new column instead of renaming an existing one, postponing the deletion of the deprecated column until the release has been successfully installed.Although Excel actions can handle most Excel automation scenarios, SQL queries can retrieve and manipulate significant amounts of Excel data more efficiently. Provides a more extensive set of properties that allow us to define what's allowed on what's not on each different environment. Since we only work with one DB type across services we wouldn't take much advantage of this feature.įlyway on the other hand has the advantage on being actively working on the integration with PostgreSQL 11, for it's upcoming version 6. Liquibase puts a lot of emphasis on independence with the DB, allowing you to create the scripts on formats like JSON and YML, abstracting away from SQL, which it's also supported. At first sight both tools look very alike, are well integrated with Spring, have a fairly frequent development activity and short release cycles. We were looking for a tool to help us integrating the migration scripts as part of our Deployment. Flyway vs Liquibase #Migration #Backwards-compatible ![]()
