To query all columns for a specific value in MySQL, you can use the SELECT statement with the * wildcard to select all columns and the WHERE clause to specify the value to search for. Here’s an example query:
SELECT * FROM table_name WHERE column_name = 'value';Replace table_name with the name of your table and column_name with the name of the column you want to search for the value in. Replace 'value' with the actual value you want to search for.
If you want to search for the same value in multiple columns, you can use the OR operator in the WHERE clause. Here’s an example query:
SELECT * FROM table_name WHERE column1 = 'value' OR column2 = 'value' OR column3 ='value';Replace column1, column2, and column3 with the names of the columns you want to search for the value in. Replace 'value' with the actual value you want to search for.
