Build 22.0.8462

Miscellaneous

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


PropertyDescription
AutoDetectIndexA boolean indicating if secondary indexes should be automatically detected based on the query used.
BatchSizeThe maximum size of each batch operation to submit.
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.
FlexibleSchemaSet FlexibleSchema to true to scan for additional metadata on the query result set. Otherwise, the metadata will remain the same.
GenerateSchemaFilesIndicates the user preference as to when schemas should be generated and saved.
IgnoreTypesRemoves support for the specified types. For example, Time. These types will then be reported as strings instead.
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.
MaximumRequestRetriesThe maximum number of times to retry a request.
MaxRowsLimits the number of rows returned rows when no aggregation or group by is used in the query. This helps avoid performance issues at design time.
OtherThese hidden properties are used only in specific use cases.
PagesizeThe maximum number of results to return per page from Amazon DynamoDB.
PseudoColumnsThis property indicates whether or not to include pseudo columns as columns to the table.
ReadonlyYou can use this property to enforce read-only access to Amazon DynamoDB from the provider.
RetryWaitTimeThe minimum number of milliseconds the provider will wait to retry a request.
RowScanDepthThe maximum number of rows to scan to look for the columns available in a table.
RTKThe runtime key used for licensing.
SeparatorCharacterThe character or characters used to denote hierarchy.
ThreadCountThe number of threads to use when selecting data via a parallel scan. Setting ThreadCount to 1 will disable parallel scans.
TimeoutThe value in seconds until the timeout error is thrown, canceling the operation.
TypeDetectionSchemeDetermines how to determine the data type of columns.
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.
UseBatchWriteItemOperationWhen enabled the provider will use BatchWriteItem operation for handling updates and inserts. By default, the provider uses ExecuteStatement/BatchExecuteStatement operation. You need to enable BatchWriteItem only when inserting/updating binary/binary-set data. ExecuteStatement/BatchExecuteStatement doesn't support manipulating binary fields.
UseConsistentReadsWhether to alyways use Consistent Reads or not when querying DynamoDb.
UserDefinedViewsA filepath pointing to the JSON configuration file containing your custom views.
UseSimpleNamesBoolean determining if simple names should be used for tables and columns.
