Property | S/T | Description |
|---|---|---|
Encoding | S/T | Type of encoding to use with source and target files. Default value is OEM. |
WhereStmt | S | Provides a mechanism for advanced users to construct the Where clause of the SQL query to filter the incoming records. There is no default value for this property. Note: This property is not applicable when the source connection is a query statement or file. This property enables data filtering when you select a table. |
SystemTables | S/T | When set to TRUE, this property allows you to see all tables that were created by the DBA. That is, the system table names appear in the table list. Default value is FALSE. Note: This property is applicable only if the user is logged onto the database as a DBA. Only the DBA has access to system tables. |
Views | S/T | When set to TRUE, this property lists all the view names along with the table names. Default value is TRUE. Note: This property supports only Append and DeleteAndAppend output modes and does not support the Replace output mode. |
CursorType | S | Specifies the type of cursor to use for retrieving records from the source table. The available options are: • dynamic • static • forward only (default) For more details, see Cursors. |
DriverCompletion | S/T | Controls how the ODBC driver prompts for missing information. The available options are: • prompt - asks the user all information. • complete (default) - asks the user for information they forgot to enter. • complete required - asks the user only for information required to complete the connection. • no prompt - does not asks the user for any information. |
IdentifierQuotes | S/T | All databases have what are called quoted identifiers. You enclose identifiers in quotes to make the SQL statement parseable and to distinguish between columns and character data. For example, Oracle uses double quotes (") for column and table names and single quotes (') for character data. In a SQL statement, you should enclose identifiers containing special characters or match keywords in identifier quote characters; (also known as delimited identifiers in SQL-92). For example, the Accounts Receivable identifier is in quotes in the following SELECT statement: SELECT * FROM "Accounts Receivable" If you do not use identifier quotes, the parser assumes there are two tables, Accounts and Receivable and return a syntax error that they are not separated by a comma. The available options are: • Default • " |
ModifyDriverOptions | S/T | Allows you to store the ODBC driver connection information. The available options are: • TRUE (default) - Store the ODBC connection information. • FALSE - Prompt for connection information each time the transformation is run. |
DriverOptions | S/T | Specify valid ODBC driver string connection options. There is no default value for this property. |
MaxDataLength | S/T | Specifies the maximum data length for long data types. The default value is 1 MB. You can reset this number based on your available memory and target requirements. When this connector requests the column field size for these data types, it checks for a returned value greater than the MaxDataLength value. If the value is greater, the MaxDataLength value is used. Some ODBC drivers have maximum data length limitations. If you choose an ODBC source or target connector and the default setting is not 1 MB, the integration platform sets the value for that particular ODBC driver. Under those conditions, do not set the MaxDataLength property to a higher value. |
TransactionIsolation | S/T | Allows you to specify an isolation level to use when reading from or writing to a database table with ODBC. The ANSI SQL 2 standard defines three specific ways in which serializability of a transaction may be violated: P1 (Dirty Read), P2 (Nonrepeatable Read), and P3 (Phantoms). The available options are: • read uncommitted – Permits P1, P2, and P3. • read committed – Permits P2 and P3. Does not permit P1. • repeatable read – Permits P3. Does not permit P1 and P2. • serializable (default) – Does not permit P1, P2 or P3. For further details about TransactionIsolation levels, refer to IBM DB2 Universal Database ODBC documentation. |
ConstraintDDL | T | Allows to specify Data Definition Language (DDL) statements to set table constraints after they are created. This is similar to support provided for SQL pass-through in the SQL import connectors. Each line must be a valid ODBC DDL statement. This property has no default. For an example, see ConstraintDDL Example. |
CommitFrequency | T | Allows users to specify the number of records to insert or update before issuing a commit to the database. This property is applicable only if the AutoCommit property is set to FALSE. The default value is zero that is, the data is committed at the end of the transformation, allowing rollback on error. This is the slowest setting. When performing large transformations, this is not practical as it may produce too many transaction log entries. |
AutoCommit | T | When set to TRUE, it automatically commits changes as they are made by each SQL statement, instead of waiting until the end of the transaction. Also, if this option is set to TRUE, you cannot roll back changes after they are done. It will overwrite the CommitFrequency value, which means that the changes are committed by each SQL statement irrespective of the value set for CommitFrequency. The default value is FALSE. |
BulkOperations | T | Specifies whether or not to use bulk operations for faster insert. If set to TRUE, an insert statement or bulk add is executed for each record. This allows you to maximize speed. The default value is FALSE, the slower setting. |
PrimaryKey | T | Allows to specify a list of comma separated field names that are used to create a primary key. If this property contains one or more field names, these names are included in the SQL CREATE statement when the connector is in replace mode. This property has no default. To use this property, your ODBC driver must support integrity enhancement facility (IEF). Only the more advanced ODBC drivers support this. |
ArraySize | T | Determines the number of rows to be sent to the server at one time. The default value is 1000. Larger values will buffer multiple rows and send them all at once. While this improves the speed, it affects error reporting (a server error won't be detected/reported until the next batch of records is sent to the server). The maximum value allowed for this property is 100000. While the connector allows the value to be set that high, many drivers have lower limits. The connector will log a message indicating if the driver is forcing a lower value for the array size. In addition, the connector does not support arrays when there is a LOB-type field in the table, or when the (maximum) length of a character-type field is longer than 32767 characters. In these cases, a message will be logged indicating the array size has been reduced to 1. Due to the way the connector attempts to support older drivers, the array support requires BulkOperations and UseCursors is set to TRUE or both must be set to FALSE. If BulkOperations is FALSE and UseCursors is TRUE, then the array size is ignored and a message is logged indicating this condition. |
StripLeadingBlanks | S/T | Strips out leading blanks in all data fields if set to true. Default is false. Note: This property is applied to the source connector only if Source Table/View is set to Table/View. It is not applied if Source Table/View is set to Query Statement or Query Files. |
StripTrailingBlanks | S/T | Strips out trailing blanks in all data fields if set to true. Default is false. Note: This property is applied to the source connector only if Source Table/View is set to Table/View. It is not applied if Source Table/View is set to Query Statement or Query Files. |
