このセクションでは、本プロバイダーの接続設定で設定可能なMiscellaneous プロパティの全リストを提供します。
プロパティ | 説明 |
AllowPreparedStatement | クエリステートメントを実行前に準備します。 |
COPYConversionParameters | Specifies the coma separated list of parameter to use in the COPY command when InsertMode is S3Staging or S3StagingWithIAM. Supported parameters are: BLANKSASNULL DELIMITER EMPTYASNULL EXPLICIT_IDS NULL AS TRIMBLANKS TRUNCATECOLUMNS |
FetchResultSetMetadata | This field sets whether the provider retrieves metadata pertaining to the schema and table name for resultset columns returned by the server. |
IncludeTableTypes | If set to true, the provider will query for the types of individual tables and views. |
InsertMode | Specifies what method to use when inserting bulk data. By default DML mode is used. |
LZ4Compression | When set the driver notifies the server to compress data packets with lz4 compression algorithm. |
MaxRows | クエリで集計またはGROUP BY を使用しない場合に返される行数を制限します。これはLIMIT 句よりも優先されます。 |
Other | これらの隠しプロパティは特定のユースケースでのみ使用されます。 |
QueryPassthrough | このオプションは、クエリをAmazon Redshift サーバーにas-is で渡します。 |
Readonly | このプロパティを使用して、provider からAmazon Redshift へのアクセスを読み取り専用に設定できます。 |
RedshiftToS3RoleARN | The Amazon Resource Name of the role to use when authenticating S3 with IAM role by the COPY command for the bulk inserts. |
RTK | ライセンス供与で使用されるランタイムキー。 |
S3Bucket | Specifies the name of AWS S3 bucket to upload bulk data for staging. |
S3BucketFolder | Specifies the name of the folder in AWS S3 bucket to upload bulk data for staging. By default bulk data are staged in the root folder. |
StripOutNulls | When set the null characters are stripped out from character values in bulk operations. |
Timeout | タイムアウトエラーがスローされ、処理をキャンセルするまでの秒数。 |
TimeZone | 現在のセッションのタイムゾーンを設定します。 |
UseUIDForStaging | Use this property in combination with InsertMode assigned with S3Staging or S3StagingWithIAM. By default the the driver creates staging files with names that prepend the targeted table's name, so the files are overwritten between sessions. When the property is set to True , the provider additionally attaches temporary unique identifiers to these names. It may be required if you use parallel jobs to insert rows into the same table. Thus, the staging files are not overwritten by the jobs. A caveat is that using this property adds to the number of staging files put onto S3 bucket, since the file names are not controlled by the driver between different sessions. In this case you may want to define an AWS S3 policy on the bucket to remove staging files that were stored in a bucket automatically. |
