Method Detail

splitSqlScript

public static void splitSqlScript(String resource,
                                  String script,
                                  String separator,
                                  String commentPrefix,
                                  String blockCommentStartDelimiter,
                                  String blockCommentEndDelimiter,
                                  List<String> statements)

Split an SQL script into separate statements delimited by the provided separator string. Each individual statement will be added to the provided List.

Within the script, the provided commentPrefix will be honored: any text beginning with the comment prefix and extending to the end of the line will be omitted from the output. Similarly, the provided blockCommentStartDelimiter and blockCommentEndDelimiter delimiters will be honored: any text enclosed in a block comment will be omitted from the output. In addition, multiple adjacent whitespace characters will be collapsed into a single space.

Parameters:

resource - the resource from which the script was read

script - the SQL script; never null or empty

separator - text separating each statement — typically a ';' or newline character; never null

commentPrefix - the prefix that identifies SQL line comments — typically "--"; never null or empty

blockCommentStartDelimiter - the start block comment delimiter; never null or empty

blockCommentEndDelimiter - the end block comment delimiter; never null or empty

statements - the list that will contain the individual statements

containsSqlScriptDelimiters

public static boolean containsSqlScriptDelimiters(String script,
                                                  String delim)

Does the provided SQL script contain the specified delimiter?

Parameters:

script - the SQL script

delim - String delimiting each statement - typically a ';' character

executeSqlScript

public static void executeSqlScript(Connection connection,
                                    String scriptPath,
                                    String script)
                             throws ScriptException

Throws:

ScriptException

executeSqlScript

public static void executeSqlScript(Connection connection,
                                    String scriptPath,
                                    String script,
                                    boolean continueOnError,
                                    boolean ignoreFailedDrops,
                                    String commentPrefix,
                                    String separator,
                                    String blockCommentStartDelimiter,
                                    String blockCommentEndDelimiter)
                             throws ScriptException

Execute the given SQL script.

Statement separators and comments will be removed before executing individual statements within the supplied script.

Do not use this method to execute DDL if you expect rollback.

Parameters:

connection - the JDBC connection to use to execute the script; already configured and ready to use

scriptPath - the resource (potentially associated with a specific encoding) to load the SQL script from

script - the raw script content

continueOnError - whether or not to continue without throwing an exception in the event of an error

ignoreFailedDrops - whether or not to continue in the event of specifically an error on a DROP statement

commentPrefix - the prefix that identifies comments in the SQL script — typically "--"

separator - the script statement separator; defaults to ";" if not specified and falls back to "\n" as a last resort

blockCommentStartDelimiter - the start block comment delimiter; never null or empty

blockCommentEndDelimiter - the end block comment delimiter; never null or empty @throws ScriptException if an error occurred while executing the SQL script

Throws:

ScriptException
