dbimport create options
The dbimport utility supports options for creating a database, specifying a dbspace for that database, defining logging options, and optionally specifying ANSI/ISO-compliance or NLS case-insensitivity (or both) as properties of the database.
| Element | Purpose | Key Considerations |
|---|---|---|
| -ansi | Creates an ANSI/ISO-compliant database in which the ANSI/ISO rules for transaction logging are enabled. Otherwise, the database uses explicit transactions by default. | If you omit the -ansi option, the database
uses explicit transactions. Additional Information: For more information about ANSI/ISO-compliant databases, see the HCL OneDB™ Guide to SQL: Reference. |
| -ci | Specifies the NLS case-insensitive property. Otherwise, the database is case-sensitive by default. | Additional Information: See the HCL OneDB Guide to SQL: Syntax and HCL OneDB Guide to SQL: Reference descriptions of the NLS case-insensitive property. |
| -d dbspace | Specifies the dbspace where the database is created. . | If this is omitted, the default location is the root dbspace |
| -l | Establishes unbuffered transaction logging for the imported database. If the -l flag is omitted, the database is unlogged, | References: For more information, see Database-logging mode. |
| -l buffered | Establishes buffered transaction logging for the imported database. If -l is included but buffered is omitted, the database uses unbuffered logging. | References: For more information, see Database-logging mode. |
If you created a table or index fragment containing partitions in OneDB Version 10.00 or a later version of the HCL OneDB database server, you must use syntax containing the partition name when importing a database that contains multiple partitions within a single dbspace. See the HCL OneDB Guide to SQL: Syntax for syntax details.
Example showing dbimport create options (UNIX™ or Linux™)
To import the stores_demo database from the /usr/informix/port/stores_demo.exp directory, issue this command:
dbimport -c stores_demo -i /usr/informix/port -l -ansiThe new database is ANSI/ISO-compliant.
The next example similarly imports the stores_demo database from the /usr/informix/port/stores_demo.exp directory. The imported database uses buffered transaction logging and explicit transactions. The -ci flag specifies case insensitivity in queries and in other operations on columns and character strings of the NCHAR and NVARCHAR data types:
dbimport -c stores_demo -i /usr/informix/port -l buffered -ciThe -ansi and -ci options for database properties are not mutually exclusive. You can specify an ANSI/ISO-compliant database that is also NLS case-insensitive, as in the following example of the dbimport command:
dbimport -c stores_demo -i /usr/informix/port -l -ansi -ciExample showing dbimport create options (Windows™)
To import the stores_demo database from the C:\USER\informix\port\stores_demo.exp directory, issue this command:
dbimport -c stores_demo -i C:\USER\informix\port -l -ansiThe imported database is ANSI/ISO-compliant and is case-sensitive for all built-in character data types.
