Is it possible to find the number of columns in a tabl

Answer 1

Since all answers are using COUNT(), you can also use MAX() to get the number of columns in a specific table as

SELECT MAX(ORDINAL_POSITION) NumberOfColumnsInTable
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_CATALOG = 'YourDatabaseNameHere'
      AND 
      TABLE_SCHEMA = 'YourSchemaNameHere'
      AND
      TABLE_NAME = 'YourTableNameHere';

See The INFORMATION_SCHEMA COLUMNS Table
