Search multiple files

[AFgh24]

Hello
I need to search in some parquet files
But it only searches the first file
It does not search the second or third file

dsq user1.parquet userdata2.parquet "SELECT * FROM {} WHERE user REGEXP 'test'" > result.csv

Please help me

You need to follow the multiple file syntax and use a UNION to go across them.

So (SELECT * FROM {1} UNION SELECT * FROM {2}) WHERE user REGEXP 'test'.
