Import tool: SAP Sybase ASE Database 15 (
Import interface: [Relational Database] Data Store (Physical Data Model, Stored Procedure Expression Parsing) via JDBC API from SAP Sybase ASE Database (via JDBC)
Import bridge: 'JdbcSybase' 10.1.0


This bridge establishes a JDBC connection with a physical database in order to extract the physical metadata. It is critical that the parameters are filled correctly for the local connection requirements on the client workstation that runs the bridge.
Note, that you must specify the driver path (jconn3d.jar and jTDS3d.jar) to use this bridge.

Please refer to the individual parameter tools tips for more detailed examples by database type.

Driver details:
- driver name: jConnect (TM) for JDBC (TM) (com.sybase.jdbc3.jdbc.SybDriver)
- driver version: jConnect (TM) for JDBC(TM)/6.05(Build 26023)/P/EBF14466/DEBUG/JDK14/Thu Mar 15 1:01:34 2007
- files: jconn3d.jar (578,426 bytes), jTDS3d.jar (195,012 bytes)
- files location: ${MODEL_BRIDGE_HOME}/java/Jdbc/sybase

Bridge Parameters

Parameter Name Description Type Values Default Scope
Driver location
This parameter is optional.

By default, all necessary JARs will be loaded from:

However, you may use this parameter to specify a different location. All JARs found in the specified folder will be added to the CLASSPATH.

The 'com.sybase.jdbc3.jdbc.SybDriver' JDBC driver with the 'jConnect (TM) for JDBC (TM)' name is required.
Host Host name or IP address where the database server is running. STRING   localhost Mandatory
Port Database engine service port number. Default value is 5000. NUMERIC   5000 Mandatory
User The database user name on whose behalf the connection is being made.

Important note about permissions:
This bridge reads the metadata for a database, rather than the data. Hence, permission assignments need to be quite different than for a standard database user. The bridge requires access to the system tables, not the actual data tables, thus it is highly recommended that one engages with their DB Admin staff to ensure proper permissions for the username entered here.

We do not have any specific instructions as to what are the minimal set of permissions required as it varies from different types of databases, as well as different versions. In order to ensure that the bridge is working properly, one must first import using the bridge with a FULL Sys Admin type username (all permissions), i.e., the same type of username that is used to create and maintain the DB. Once the bridge is working properly against a given DB, then the DB Admin staff may create a user with lesser privileges that still produce a successful result.

Note, this parameter is not required. In the case of Oracle and Microsoft SQL Server one can specify user credentials in the cHost bridge parameter. In addtion, many Microsoft Access databases allow one to connect without specifying user credentials.
Also, for the Microsoft SQL Server specific bridge, if this parameter is empty, then it is assumed that integrated security is being used (see In this case, the bridge will attempt to connect with this type of signature:

jdbc:sqlserver://; integratedSecurity=true
instead of

jdbc:sqlserver://; user=userid;password=userpassword

However, in order for this to work, the user must the sqljdbc_auth.dll available on the PATH environment variable. Also the version of the library must match the version of the sqljdbc4.jar that they are using.
Password The database user's password on whose behalf the connection is being made PASSWORD      
Database This option can be used as a constraint to import a specific database by its name.

The possible values are one database name: only the schemas and tables that belong to this database will be imported.

AdventureWorksDW - import tables from the 'AdventureWorksDW' database.
Schema Description: you can specify a list of database schemas to import.
When the list is empty all available schemas are imported.
The list can have one or more schema names separated by semicolons (e.g. schema1; schema2).
You can specify schema name patterns using SQL LIKE expressions syntax.
Patterns support inclusions and exclusions.
Here is an example of inclusion syntax, "A%; %B; %C%; D" that tries to get schema names that:
- start with A or
- end with B or
- contain C or
- equal D

Note: when a pattern has special characters, like spaces enclose it in single quote marks (e.g. "'two wo%'; onewo%;").

To exclude a pattern prefix it with NOT. Here is an example of exclusion syntax, "A%; %B; NOT %SYS; NOT 'SYS%'"
that contributes to the following SQL filter: "where (name like A% or name like %B) and (name not like %SYS) and (name not like 'SYS%')"
Stored procedure details Specify what stored procedure details you would like to include

- 'Signature' - name and parameters of stored procedures (default)
- 'Code, signature' - above plus code
- 'None' - stored procedures are not included
Code, signature
Import indexes Specifies if the Indexes should be imported or not.

- 'False' : Indexes are not imported(default)
- 'True' : Indexes are imported
Miscellaneous Specify miscellaneous options identified with a -letter and value.

For example, -m 4G -f 100 -j -Dname=value -Xms1G

-f the database driver fetch size in number of rows (e.g. -f 100)

-zip exportFile to store DDL create tables statements (e.g -zip c:/temp/ddl/

-m the maximum Java memory size whole number (e.g. -m 4G or -m 2500M ).
-s import system objects that are skipped by default (e.g. -s)
-v set environment variable(s) (e.g. -v var1=value -v var2="value with spaces").
-j the last option that is followed by Java command line options (e.g. -j -Dname=value -Xms1G).

-diff difference detection level (e.g. -diff ikm for disabling checking indexes, keys, classifier and feature maps)

-synonyms disable import of all synonyms
