A string that specifies the location of source and object components needed to build the table function.
For more information, see SQL Data Definition Language - Detailed Topics, B035-1184.
Single character code. Depending on the initial code in the sequence, the string specifies either the table function object name for the UDF or an encoded name or path for the components needed to create the table function.
- Function object. The string that follows is the entry point name of the C or C++ table function object.
- Client. The source or object code for the table function is stored on the client.
- Server. The source or object code for the table function is stored on the server.
Following is a list of the path specifications for the external table function. The options may be repeated as many times as needed with the exception of the package option. You can specify the following file types as external string literals.
- Include file (.h).
- Library name for a nonstandard library files needed by the UDF.
- Object file.
- Package name. You cannot use the package option with any other options except F, the C function name option.
- Source file.
- No source file. Source files and include files are not stored in the function table. This option only affects how source code is processed in the creation of a new function and applies to all source code specified in the external string literal.
- Specify a delimiter character, such as !. You must use the same delimiter throughout the string specification.
- Name the file on the server. Include files must have the same name specified in the include statement in the C source, without the extension.
- Location (path) and name of the source, include file, object, or library. Because packages and libraries must be preinstalled, you must use the server option (S). Path specifications can use forward slashes (/) or backward slashes (\) regardless of whether the function is being created on a Unix or Windows platform.
Java Table Function Variables
The following variables apply to Java table functions only.
- The registered name of the JAR file associated with this function.
- The name of the Java class contained within the JAR that contains the Java method to be executed.
- The name of the method executed when the UDF is executed.
- See SQL Fundamentals for the rules for naming database objects.
- A primitive parameter class as one of the following:
- An object parameter class definition in the format:
