Actian Zen/PSQL v13 Multimode
Actian Zen is a zero-maintenance, embedded, high-performance Database Management System (DBMS) for Edge data management-whether in the Cloud, remote and branch offices or in mobile and IoT settings. Actian PSQL v13 and later is called Actian Zen. For information about Actian Zen, see the Actian Zen documentation available at

Connector-Specific Notes
Target schema modification - Column names, data types, and sizes cannot be modified.
Query statement support - The target format must support query statements such as Oracle and SQL Server statements, for transformation to work with this connector.
Auto-increment fields - If the target table contains an auto-increment column, you may see an error at run time. If this occurs, delete the field that is causing the problem.
Auto-generated GUID - You can use an EZScript to auto-generate a GUID for a variable declared as the unique identifier data type. See Generating a Random Unique Identifier.
Connector Properties
You can set the following source (S) and target (T) properties.
Type of encoding to use with source and target files. The default value is OEM.
SQL Output
Output mode for SQL statements. There are four output modes:
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.
Note:  Bound mode is faster since bind variables are used.
SQL log file in the default installation directory. The default file name is sql.log. To use a different log, browse to the file or enter the path and file name.
If set to true, null values are sent to the database when inserting or updating records.
If set to false, null values are not sent to the database when inserting or updating records. Also, this property forces the connector to operate in unbound mode, which may cause slower performance.
The default value is false.
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.
If set to true, allows you to see all tables created by the Database Administrator (DBA) in the database. The system table names appear in the table list. The default value is false.
Note:  This property is applicable only if you have logged in to the database as the DBA. Only the DBA has access to system tables.
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.
Automatically commit changes as they are made by each SQL statement, instead of waiting until the end of the transaction. If this option is set to true, you cannot roll back the changes after they are done. The default value is false.
Quoted identifiers are used to parse the SQL statement and distinguish between columns and character data in SQL statements. All databases have quoted identifiers.
In a SQL statement, you must 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 return a syntax error that they are not separated by a comma.
IdentifierQuotes has four options:
Maximum number of characters to write to a field. It is the maximum data length for long data types. The default value is 1 MB. You can change this value based on the 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, then 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. In this case, do not set the MaxDataLength property to a higher value.
Allows you to specify an isolation level when reading from or writing to a database table with ODBC. The isolation levels 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 – Does not permit P1, P2 or P3.
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).
For further details about TransactionIsolation levels, see the IBM DB2 Universal Database ODBC documentation.
