Find value in any column in a table

[Adil]

Hi,

I'm not sure if this is a possible scenario, but is there, by any chance a way to query all the columns of a table for searching a value? 

Explanation: I want to search for a specific value in all the columns of a databricks table. I don't know which column that value might be present, or not. I just am not sure what column holds that value. 

Thoughts?

Hi @Adil, Certainly! When you need to search for a specific value across all columns in a table, you can use SQL queries to achieve this. You can construct a query that checks each column for the desired value.

Here are a few approaches you can consider:

Concatenating Columns:

• You can concatenate all the columns’ values and perform a LIKE search. This approach works well when finding the value anywhere in the concatenated string.
• Note that this method may not work well for columns with numeric data types.

Dynamic Query:

• If you want a more dynamic solution, you can generate a query that searches across all columns without explicitly listing them.
• This approach dynamically constructs a query to search for the specified value in all columns of the given table.
