-------------------------------------------

             Summary: Support "IF EXISTS/IF NOT EXISTS" for all clauses of "ALTER TABLE"
                 Key: CASSANDRA-14706
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-14706
             Project: Cassandra
          Issue Type: New Feature
            Reporter: Dmitry Lazurkin


Like so:
{noformat}
ALTER TABLE <table> ALTER <column> TYPE <newtype>;
ALTER TABLE [ IF EXISTS ] <table> ADD [ IF NOT EXISTS ] <coumn> <newtype>;
ALTER TABLE [ IF EXISTS ] <table> ADD [ IF NOT EXISTS ] (<column> <newtype>,<column1> <newtype1>..... <column n> <newtype n>);
ALTER TABLE [ IF EXISTS ] <table> DROP [ IF EXISTS ] <column>;
ALTER TABLE [ IF EXISTS ] <table> DROP [ IF EXISTS ] ( <column>,<column1>.....<column n>);
ALTER TABLE [ IF EXISTS ] <table> RENAME [ IF EXISTS ] <column> TO <column>;
ALTER TABLE [ IF EXISTS ] <table> WITH <property> = <value>;
{noformat}

I think common IF EXISTS/IF NOT EXISTS clause for ADD/DROP better than clause for each column.
