Need Help with Formatting DateTime in Azure Synapse Data Flow Expression Language

HamidBee — Wed, 13 Dec 2023 23:18:51 GMT

Hi All,

I'm working with Azure Synapse Analytics and I'm facing an issue with the Data Flow expression builder. My goal is to format a column named "Start Date (BST)" which currently has the format yyyy-MM-ddTHH:mm:ss.SSSSSS to dd/MM/yyyy HH:mm:ss, effectively removing the milliseconds.

Here's what the date looks like right now:

2022-07-07T23:43:13.722007

I tried using the following expression in the data flow expression builder:

toTimestamp('Start Date (BST)', 'dd/MM/yyyy HH:mm:ss:SS')

However, I am getting an error stating "Unable to parse the expression. Please make sure it is valid."

Could someone please guide me on the correct syntax or the steps I should take to format the datetime values properly using the expression builder in Azure Synapse? I would appreciate any insights or examples of the correct expression to achieve this.

Thank you in advance!
