Property | Description |
|---|---|
AutoCommit | If set to True, it allows you to automatically commit 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. |
DriverCompletion | Allows you to control whether or not the driver prompts you for information. The options available are Prompt, Complete, Complete Required, No Prompt. The Prompt option prompts you for every individual bit of information. Complete prompts you for any information they forgot to enter. The Complete Required option prompts you only for information that is essential to complete the connection. The No Prompt option does not prompt you for any information. The default is Complete. |
DriverOptions | Specify a valid ODBC driver string connection. The default is empty for a new map. This property can be specified or edited when one of the following is true: • The Source Data Source" is selected and the DSNType is set to "Driver". • All source connection parts are specified and the map is connected to the data. In this case, the connector builds the DriverOptions for you based on the connection parts you enter. Users can edit the pre-built options string as needed. |
DSNType | Data sources or drivers to connect to in the Data Source Name (DSN) list. DSNs are listed in Control Panel > Administrative Tools > ODBC Data Source Administrator window. The options are: • User & System: This is the default option. • System: This DSN allows database access for any user of a particular computer. The System DSN are stored in the Windows registry. • User: This DSN allows database access for a single user on a single computer. Like the System DSN, the information is stored in the Windows registry. • Driver: The ODBC driver to connect to. This driver must be installed on your computer. • File: This DSN stores information required to connect to the desired data source in a text file with a .DSN extension (not in the Windows registry) and can be shared by users of different computers who have the same drivers installed. For more information, see Configuring ODBC Data Source. |
IdentifierQuotes | All databases have what are called quoted identifiers. You use quoted identifiers to make the SQL statement parseable and distinguish between columns and character data in SQL statements. For example, Oracle uses double quotes for column and table names in SQL statements and uses 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 quoted 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 returns a syntax error that they are not separated by a comma. If either of the following values contain a space, set the identifierQuotes property on the source and the target to ““ or Default: • the value of the source connector part Table/View field. • the value of a source column name (for example, Account Number). Otherwise, if the IdentifierQuotes property is set to None, a SQL error is returned and the source table data is not displayed. IdentifierQuotes has the following options: • Default • None • " |
MaxDataLength | The maximum data length for long data types. Default is 1 MB. You can reset this number as you choose based on your available memory capabilities and Target requirements. Some ODBC drivers have limitations concerning the maximum data length they can handle. If you choose an Application (ODBC) Source or target connector and the default setting is not 1 MB, then the integration platform sets the default for the capabilities of that particular ODBC driver. It is not recommended that the MaxDataLength property be set any higher under those conditions. |
ModifyDriverOptions | Allows you to store the ODBC connection. The default is true. If you set this to false, you are prompted for your connection information each time that you run your transformation. |
SQL Output | Allows you to select bound or unbound mode and whether you want to write SQL statements to a SQL log or not. Keep in mind that bound mode is faster, since bind variables are used. • Target Only (Default) - Uses bound mode, which uses bind variables. SQL statements are sent to the Target and not to the SQL log specified in the SQL Log property. • Target Only (Unbound Mode) - Uses unbound mode, which does not use bind variables and sends the literal SQL statement to the database engine. SQL statements are sent to the Target and not to the SQL log specified in the SQL Log property. • Target and SQL Log - Sends SQL statements to the Target and to the SQL log specified in the SQL Log property. • SQL Log Only - Sends SQL statements only to the SQL log file specified in the SQL Log property. |
SQL Log | The default is sql.log in the default installation directory. To use a different log, browse to the file, or enter the path and file name. Note: SQL statements are sent to the SQL Log file only if the SQL Output property is set to either Target and SQL Log or SQL Log Only. |
UpdateNullFields | Null values are sent to the database when inserting or updating records. The default is true. If you select False, null values are not sent to the database when you insert or update records. When set to false, this property forces the connector to operate in unbound mode, which may cause slower performance. Best Practice — If fields in the target record are not mapped, then the null values are passed to the target. If you do not want to write to these fields, then it is recommended to set the value for UpdateNullFields to False. |
Synonyms | If set to true, this property allows you to see synonyms. The alias names appear in the table list along with the tables. Default is false. |
SystemTables | The SystemTables property is only applicable if you are logged onto the database as the database administrator. Only the DBA has access to SystemTables. If set to true, this property allows you to see all the tables created by the DBA. The system table names appear in the table list. The default is false. |
TransactionIsolation | The Translation Isolation option allows you to specify any one of five different isolation levels when reading from or writing to a database table with ODBC. The default is Serializable. 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 following lists the four supported isolation levels. • 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 - Does not permit any of P1, P2, and P3. For further details about TransactionIsolation levels, see the Microsoft ODBC SDK documentation. |
Views | If set to True, this property allows you to see the view names in the table list along with the table names. Default is True. Note: This property supports only Append and DeleteAndAppend output modes and does not support the Replace output mode. |
Encoding | Sets the character encoding for ODBC 3.x source and target files. Note: Shift-JIS encoding is used only in Japanese operating systems. UCS-2 is no longer a valid encoding name, but you may use UCS2 by changing the string value in the XML file. |
