getDelete()
public Mutation.Delete getDelete()
Delete rows from a table. Succeeds whether or not the named
rows were present.
.google.spanner.v1.Mutation.Delete delete = 5;
getDeleteOrBuilder()
public Mutation.DeleteOrBuilder getDeleteOrBuilder()
Delete rows from a table. Succeeds whether or not the named
rows were present.
.google.spanner.v1.Mutation.Delete delete = 5;
getInsert()
public Mutation.Write getInsert()
Insert new rows in a table. If any of the rows already exist,
the write or transaction fails with error ALREADY_EXISTS.
.google.spanner.v1.Mutation.Write insert = 1;
getInsertOrBuilder()
public Mutation.WriteOrBuilder getInsertOrBuilder()
Insert new rows in a table. If any of the rows already exist,
the write or transaction fails with error ALREADY_EXISTS.
.google.spanner.v1.Mutation.Write insert = 1;
getInsertOrUpdate()
public Mutation.Write getInsertOrUpdate()
Like insert, except that if the row already exists, then
its column values are overwritten with the ones provided. Any
column values not explicitly written are preserved.
When using insert_or_update, just as when using insert, all NOT
NULL columns in the table must be given a value. This holds true
even when the row already exists and will therefore actually be updated.
.google.spanner.v1.Mutation.Write insert_or_update = 3;
getInsertOrUpdateOrBuilder()
public Mutation.WriteOrBuilder getInsertOrUpdateOrBuilder()
Like insert, except that if the row already exists, then
its column values are overwritten with the ones provided. Any
column values not explicitly written are preserved.
When using insert_or_update, just as when using insert, all NOT
NULL columns in the table must be given a value. This holds true

getParserForType()

getReplace()
public Mutation.Write getReplace()
Like insert, except that if the row already exists, it is
deleted, and the column values provided are inserted
instead. Unlike insert_or_update, this means any values not
explicitly written become NULL.
In an interleaved table, if you create the child table with the
ON DELETE CASCADE annotation, then replacing a parent row
also deletes the child rows. Otherwise, you must delete the
child rows before you replace the parent row.
.google.spanner.v1.Mutation.Write replace = 4;
getReplaceOrBuilder()
public Mutation.WriteOrBuilder getReplaceOrBuilder()
Like insert, except that if the row already exists, it is
deleted, and the column values provided are inserted
instead. Unlike insert_or_update, this means any values not
explicitly written become NULL.
In an interleaved table, if you create the child table with the
ON DELETE CASCADE annotation, then replacing a parent row
also deletes the child rows. Otherwise, you must delete the
