How to bulk process a Database Delta sql file in Azure Data Factory to update a MySQL database

I have a database delta .sql file that contains updates to table in a MySql database. I understand that data factory can execute sql statements and I could parse the .sql file a csv split by delimiter of ';' to get the sql statements. However my delta file contains a large number of statements and looping this in ADF would mean it would call such activities potentially hundreds of thousands of times - is it possible to execute statements in bulk?

Reference to an implantation with iteration sql statements: How to process a Database Delta sql file in Azure Data Factory to update a MySQL database

or if there not an efficient way to update through iterating the .sql file? Is the only sensible approach a function app to execute the sql?

Many Thanks.

You can run all the queries in .sql file in a single batch itself. Below is the approach.

• Take the lookup activity and take the dataset which contains the .sql file. Give the different column delimiter and row delimiter which is not in the file itself. So that all queries will be included in a single row itself. In this demo, I gave & as delimiter.

• If you are using azure SQL database for MySQL then you can take script activity and give the below expression. If you use mySQL database, then you can use lookup activity to execute the SQL script. Give the below expression in the query text box of lookup activity/script activity.

@concat(activity('Lookup1').output.value[0].Prop_0,'select 1 as col1')

if the select 1 as col1 is not concatenated with the output of lookup activity, then ADF will throw error. Because Lookup activity expects to return data.
