SPECIFICATIONS
Tool: SAS / Base SAS Code version 9x via SAS TXT File
See http://support.sas.com/documentation/cdl/en/lrcon/65287/HTML/default/viewer.htm
Metadata: [Data Integration] Multi-Model, Data Store (Physical Data Model), (Source and Target Data Stores, Transformation Lineage, Expression Parsing)
Component: SqlScriptSas version 11.0.0

OVERVIEW
This bridge parses a directory of SAS code scripts to extract the data models of their source and target data stores (e.g. database schema, tables, columns) as well as the Data Integration (DI/ETL/ELT) models for the data flow lineage between these data stores.

The import process consists of multiple stages including SAS code interpretation that allows to extract and prepare the SQL statements for further analysis. In SAS code, the SQL queries are located inside procedure called 'PROC SQL'. The interpreter also helps to convert SAS specific expressions into the generic structures that can be recognized by the SQL parser.
This bridge allows to replace SAS variables (e.g. &var.) in SQL queries using a separate file that contains all the necessary values. For more details please refer to documentation for bridge parameter 'Miscellaneous' and the section for key '-s'.

- the metadata backup if available (can be set in the Miscellaneous parameter with option -backup)


Bridge Parameters

Parameter Name Description Type Values Default Scope
Directory The directory of SAS code files to import. DIRECTORY     Mandatory
Directory Filter Specify a search filter for the sub directories. Use regular expressions in java format if needed (e.g. '
.*_script - only directories ending with _script
directory1 directory2 - multiple conditions can be defined by using a space as a separator
\"my directory\" - names with with any space must be escaped with double quotes
-ddl - Negation can be defined with the preceding dash character
STRING      
File Filter The file filter pattern, based on the using the java format expression syntax
.*\\.sql - only files with extension .sql
file1 file2 - multiple conditions can be defined by using a space as a separator
\"my file.sql\" - names with with any space must be escaped with double quotes
-\\.tar\\.gz - Negation can be defined with the preceding dash character
STRING      
Miscellaneous Specify miscellaneous options starting with a dash and optionally followed by parameters, e.g.
-connection.cast MyDatabase1="SQL Server"
Some options can be used multiple times if applicable, e.g.
-connection.rename NewConnection1=OldConnection1 -connection.rename NewConnection2=OldConnection2;
As the list of options can become a long string, it is possible to load it from a file which must be located in ${MODEL_BRIDGE_HOME}\data\MIMB\parameters and have the extension .txt. In such case, all options must be defined within that file as the only value of this parameter, e.g.
ETL/Miscellaneous.txt

GENERAL OPTIONS
-m <Java Memory's maximum size>
1G by default on 64bits JRE or as set in conf/conf.properties, e.g.
-m 8G
-m 8000M

-j <Java Runtime Environment command line options>
This option must be the last one in the Miscellaneous parameter as all the text after -j is passed "as is" to the JRE, e.g.
-j -Dname=value -Xms1G
The following option must be set when a proxy is used to access internet (this is critical to access https://repo.maven.apache.org/maven2/ (and exceptionally a few other tool sites) in order to download the necessary third party software libraries.
-j -Dhttp.proxyHost=127.0.0.1 -Dhttp.proxyPort=3128 -Dhttps.proxyHost=127.0.0.1 -Dhttps.proxyPort=3128 -Dhttp.proxyUser=user -Dhttp.proxyPassword=pass -Dhttps.proxyUser=user -Dhttps.proxyPassword=pass

-jre <Java Runtime Environment full path name>
It can be an absolute path to javaw.exe on Windows or a link/script path on Linux, e.g.
-jre "c:\Program Files\Java\jre1.8.0_211\bin\javaw.exe"

-v <Environment variable value>
None by default, e.g.
-v var1=value1 -v var2="value2 with spaces"

-model.name <model name>
Override the model name, e.g.
-model.name "My Model Name"

-prescript <script name>
The script must be located in the bin directory, and have .bat or .sh extension.
The script path must not include any parent directory symbol (..).
The script should return exit code 0 to indicate success, or another value to indicate failure.
For example:
-prescript "script.bat arg1 arg2"

-cache.clear
Clears the cache before the import, and therefore will run a full import without incremental harvesting.
Warning: this is a system option managed by the application calling the bridge and should not be set by users.

-pppd
Create the connections and connection data sets in DI/ETL design models. This feature should only be used when intending to export to another DI/ETL tool.

-s <filepath>
Path to a file that resolves Shell parameters in either Windows (%param%) or in Linux (${param}, $1) format. This parameter can be used to define a path to the key/value pair yaml file. The path can be escaped with double quotes if it contains spaces or any special characters. The records from the file will be used to preprocess the scripts and replace the corresponding Shell parameters with the actual values. The key literals must not be decorated with the escape characters and the matching rules are case sensitive. Character colon ':' is used as a key/value pair delimiter and must be escaped with backward slash '\' if it is part of the parameter name. For example, for script 'INSERT INTO %SCHEMA1%.t1(c1) SELECT a from %SCHEMA2%.t2;' the file with the parameters can be organized in the following way. E.g.
# common shell parameter map
SCHEMA1: actual_schema1
SCHEMA2: actual_schema2
# individual script maps
"D:\\MIMB\\hive_001.hql":
${table_name}: actual_table
"D:\\MIMB\\hive_002.hql":
${year_var}: 1993

If the bridge doesn't find yaml file then it generates new one and fills it with pairs of keys/default values.
Yaml file contains "common shell parameter map" section and "individual script maps" section. The bridge takes common key/value pairs to substitute shell parameters by its values in all scripts. The section "individual script maps" contains pairs for individual scripts.

SQL SCRIPT OPTIONS
-d
Default schema. Allows to specify a schema name for the objects that don't have it defined explicitly.

-e
Encoding. This value will be used to load text from the specified script files. By default, UTF-8 will be used. E.g.
-e UTF-16
-e UTF-16BE
-e US-ASCII

-cs
Create separate connections for all database schemas
-cs c1, c2 - create separate connections for all database schemas of 'c1' and 'c2' connections
-cs app1=c.s1 - create 'app1' connection for the 's1' schema in the 'c' connection
STRING
