Field Details
DISTRIBUTED_JOINS
IfTRUE, enables the use of distributed joins in servicing the given query. Any query requiring a distributed join will succeed, though hints can be used in the query to change the distribution of the source data to allow the query to succeed. Supported values:The default value isFALSE.See Also:DISTRIBUTED_OPERATIONS
IfTRUE, enables the use of distributed operations in servicing the given query. Any query requiring a distributed join will succeed, though hints can be used in the query to change the distribution of the source data to allow the query to succeed. Supported values:The default value isFALSE.See Also:IGNORE_EXISTING_PK
Specifies the record collision error-suppression policy for inserting into or updating a table with a primary key, only used when primary key record collisions are rejected (UPDATE_ON_EXISTING_PKisFALSE). If set toTRUE, any record insert/update that is rejected for resulting in a primary key collision with an existing table record will be ignored with no error generated. IfFALSE, the rejection of any insert/update for resulting in a primary key collision will cause an error to be reported. If the specified table does not have a primary key or ifUPDATE_ON_EXISTING_PKisTRUE, then this option has no effect. Supported values:TRUE: Ignore inserts/updates that result in primary key collisions with existing records.FALSE: Treat as errors any inserts/updates that result in primary key collisions with existing records.
FALSE.See Also:PAGING_TABLE
When specified (orPAGING_TABLE_TTLis set), the system will create a paging table to hold the results of the query, when the output has more records than are in the response (i.e., whenhasMoreRecordsisTRUE). If the specified paging table exists, the records from the paging table are returned without re-evaluating the query. It is the caller’s responsibility to clear thepagingTableand other tables in theRESULT_TABLE_LIST(both returned in the response) when they are done with this query.See Also:PAGING_TABLE_TTL
Sets the TTL of the paging table. -1 indicates no timeout. Setting this option will cause a paging table to be generated when needed. ThepagingTableand other tables in theRESULT_TABLE_LIST(both returned in the response) will be automatically cleared after the TTL expires, if set to a positive number. However, it is still recommended that the caller clear these tables when they are done with this query.See Also:QUERY_PARAMETERS
Query parameters in JSON array or arrays (for inserting multiple rows). This can be used instead ofdataandrequestSchemaStr.See Also:UPDATE_ON_EXISTING_PK
Specifies the record collision policy for inserting into or updating a table with a primary key. If set toTRUE, any existing table record with primary key values that match those of a record being inserted or updated will be replaced by that record. If set toFALSE, any such primary key collision will result in the insert/update being rejected and the error handled as determined byIGNORE_EXISTING_PK. If the specified table does not have a primary key, then this option has no effect. Supported values:TRUE: Replace the collided-into record with the record inserted or updated when a new/modified record causes a primary key collision with an existing record.FALSE: Reject the insert or update when it results in a primary key collision with an existing record.
FALSE.See Also:VALIDATE_CHANGE_COLUMN
When changing a column using alter table, validate the change before applying it. IfTRUE, then validate all values. A value too large (or too long) for the new type will prevent any change. IfFALSE, then when a value is too large or long, it will be truncated. Supported values:The default value isTRUE.See Also:CURRENT_SCHEMA
Use the supplied value as the default schema when processing this SQL command.See Also:
