1. Which SQL statement should you use to add data to a table A. SELECT B. INSERT C. UPDATE D. DELETE B is the correct answer. 2. What two clauses are mandatory in an INSERT statement INSERT INTO and VALUES 3. In which clause in the INSERT statement do you identify the table that will receive the new data INSERT INTO 4.

What information must you specify in the VALUES clause of an INSERT statement You must specify one or more values to be inserted into the table.

6. What requirements must be met by the values in a VALUES clause The values must be enclosed in parentheses and, if more than one is specified, must be separated by commas. If the column names are not specified in the INSERT INTO clause, then there must be one value for each column in the table and the values must be in the same order as they are defined in the table. If the column names are specified in the INSERT INTO clause, then there must be exactly one value per specified column and those values must be in the same order as they are defined in the INSERT INTO clause. Each value with a character string data type must be enclosed in single quotes. 7. You re creating an INSERT statement to insert data into the ARTIST_TYPES table. The table includes only two columns: ART_ID and TYPE_NAME. You want to insert one row that includes the ART_ID value of 27 and the TYPE_NAME value of Gospel. Which SQL statement should you use You should use the following SQL statement: INSERT INTO ARTIST_TYPES VALUES ( 27, 'Gospel' ); 8. You re creating an INSERT statement that inserts values taken from another table. Which type of statement or clause can you use in place of the VALUES clause to pull data from that other table A. UPDATE B. SET C. SELECT D. WHERE C is the correct answer. 9. Which statement should you use to modify existing data in one or more rows in a table A. SELECT B. INSERT C. UPDATE D.

Only the rows that meet the specified condition(s) are updated. 12. You re creating an UPDATE statement to update data in the PERFORMING_ARTISTS table. You want to update the ART_ID value in the row that contains the PERF_ART_ID value of 139. The new ART_ID value is 27. Which SQL statement should you use
