Build 24.0.9060

Miscellaneous

This section provides a complete list of the Miscellaneous properties you can configure in the connection settings for this provider.


PropertyDescription
AggregationsSupportedWhether or not to support aggregations in the Cassandra server. Note that in queries to the provider, you must use single quotes to define strings.
AllowFilteringWhen true, slow-performing queries are processed on the server.
BatchSizeThe maximum size of each batch operation to submit.
CaseSensitivityEnable case sensitivity to the CQL sending to the server, if set to True, the identifiers in the CQL will be enclosed in double quotation marks.
ConsistencyLevelThe consistency level determines how many of the replicas of the data you are interacting with need to respond for the query to be considered a success.
DefaultDomainThis property is used for the Oracle Database Gateway for ODBC.
EnableForeignKeyDetectionWhether to detect the foreign keys in ODBC.
FlattenArraysBy default, nested arrays are returned as strings of JSON. The FlattenArrays property can be used to flatten the elements of nested arrays into columns of their own. Set FlattenArrays to the number of elements you want to return from nested arrays.
FlattenObjectsSet FlattenObjects to true to flatten object properties into columns of their own. Otherwise, objects nested in arrays are returned as strings of JSON.
IncludeDualTableSet this property to mock the Oracle DUAL table for better compatibility with Oracle database.
LimitKeySizeThe maximum length of a primary key column.
MapBigintToVarcharThis property controls whether or not the bigint type maps to SQL_VARCHAR instead of SQL_BIGINT. This property is false by default.
MapToIntThis property controls whether or not the long type maps to SQL_INTEGER instead of SQL_BIGINT. This property is false by default.
MapToLongVarcharThis property controls whether or not a column is returned as SQL_LONGVARCHAR.
MapToWVarcharThis property controls whether or not string types map to SQL_WVARCHAR instead of SQL_VARCHAR. This property is set by default.
MaximumColumnSizeThe maximum column size.
MaxRowsLimits the number of rows returned when no aggregation or GROUP BY is used in the query. This takes precedence over LIMIT clauses.
NullToUnsetUse unset instead of NULL in CQL query when performing INSERT operations.
OtherThese hidden properties are used only in specific use cases.
PagesizeThe maximum number of results to return per page from Cassandra.
PseudoColumnsSpecify a set of pseudocolumns to expose as columns.
QueryPassthroughThis option passes the query to the Cassandra server as is.
ReadonlyYou can use this property to enforce read-only access to Cassandra from the provider.
RowScanDepthThe maximum number of rows to scan to look for the columns available in a table.
RTKThe runtime key used for licensing.
TimeoutThe value in seconds until the timeout error is thrown, canceling the operation.
UpperCaseIdentifiersThis property reports all identifiers in uppercase. This is the default for Oracle databases and thus allows better integration with Oracle tools such as the Oracle Database Gateway.
UseJsonFormatWhether to submit and return the JSON encoding for CQL data types.
UserDefinedViewsA filepath pointing to the JSON configuration file containing your custom views.
VarintToStringMap Cassandra VARINT to String value.
