This feature is available in version 5.0 and later.
Using Flexible Folders
This feature can help you if you cannot use fixed-name folders in SCM under a <sql_code> root.
Using this capability, you may use any number of arbitrarily named folders under a <sql_code> root. This enables you to use folder names that are meaningful to your environment.
When you use flexible folders, the folders containing SQL code must have a metadata.properties file, even if it is blank.
You need to specify two properties (new to version 5.0) in a metadata.properties
file in the folder. They explicitly specify packaging behavior that was implicit for code in fixed-name folders.
packageMethod
- specifies how to package code in this folderrerunnable
- specify whether this code can be repackaged (updated in place)
SQL File Processing
SQL files are packaged in a determined order by type. The packaging method is determined from the type.
Ordering
Packaging is done in the following order, using the SQLFileType returned from parsing. It is the same order used with static-name directories. (Note that ddl_direct is available in 7.15 and higher.)
The following table shows the packageMethod used for each SQLFileType:
Order | SQLFileType | packageMethod |
---|---|---|
1 | ddl | CONVERT |
2 | ddl_direct | DDL_DIRECT |
3 | view | STOREDLOGIC |
4 | ssis | SSIS |
5 | ssis_project | SSIS |
6 | function | STOREDLOGIC |
7 | procedure | STOREDLOGIC |
8 | package | STOREDLOGIC |
9 | packagebody | STOREDLOGIC |
10 | trigger | STOREDLOGIC |
11 | sql | SQLFILE |
12 | sqlplus | DIRECT |
13 | sql_direct | DIRECT |
14 | data_dml | DATA_DML |
Complex and Interdependent Database Changes
Normally DDL changes are placed in folders that use the CONVERT packaging method. However, when you need to package complex and interdependent changes, place them in a folder that uses the DDL_DIRECT or DIRECT packaging method instead.
If the order that the multiple statements are listed in the single script is critical to the success of the script, then use the DDL_DIRECT or DIRECT packaging method. The DDL_DIRECT or DIRECT packaging method will preserve the order of the statements in the script. (The CONVERT packaging method may not preserve the order because it creates the change sets by doing a diff of before and after snapshots, and that comparison process does not know the original order of the statements.)
Examples of sets of statements in a single sql script that need to use the DIRECT or DDL_DIRECTpackaging method:
create table move data from old table to new table drop old table
alter table drop pk constraint alter table drop column (a column that the pk constraint depends on) alter table add column (a column that the pk constraint depends on) alter table add pk constraint
Resources Directory
During SQL file packaging, files are copied to directories under the project Resources directory. The directories have the same name except for files in sql, sqplus, and sql_direct, which are all placed in Resources/sql.
SQLFileType | Resources folder |
---|---|
DDL | N/A |
DDL_DIRECT | ddl_direct |
VIEW | view |
SSIS | ssis |
SSIS_PROJECT | ssis_project |
FUNCTION | function |
PROCEDURE | procedure |
PACKAGE | package |
PACKAGEBODY | packagebody |
TRIGGER | trigger |
SQL | sql |
SQLPLUS | sql |
SQL_DIRECT | sql |
DATA_DML | data_dml |
Properties in metadata.properties
Requirement for metadata.properties
When you are using flexible folders, folders containing SQL code must have a metadata.properties file, even if it is blank.
- Folders containing metadata.properties file are processed.
- Folders not containing metadata.properties file are skipped.
More about the different properties that can be defined in metadata.properties files: Using the metadata.properties file
ignore
Set to true or false. If true, packager skips this folder and all subfolders during processing.
packageMethod
If specified, determines the processing method to use during packaging. The file is further parsed to determine the SQLFileType, which determines the order of processing.
If not specified, determine the type based on directory location (static-name directories) and parsed SQLFileType.
- CONVERT (convert)
- STOREDLOGIC (native)
- DIRECT (native)
- DDL_DIRECT (native)
- DATA_DML (native)
- SQLFILE (native)
- SSIS (native)
rerunnable
Important: The newer rerunnable property replaces two properties in metadata.properties. These are deprecated and should not be used:
- allowRepackaging
- archive
Set rerunnable to true or false.
- true - the SQL code file is not archived. It can be repackaged.
- false - the SQL code file is archived. It cannot be repackaged.
If not set, packager checks whether fixed-name folders are being used under the <sql_code> root and assigns the rerunnable property as follows. In general, stored logic is rerunnable.
Fixed Folder | Rerunnable default setting |
---|---|
ddl | false |
ddl_direct | false |
data_dml | false |
sql_direct | false |
sql | false |
sqlplus | false |
procedure | true |
package | true |
packagebody | true |
function | true |
trigger | true |
view | true |
