Method Detail

setDelimiter

public void setDelimiter(String delimiter,
                         boolean fullLineDelimiter)

runScript

public static void runScript(Connection connection,
                             Reader reader)

Runs an SQL script (read in using the Reader parameter).

Parameters:

connection - the database connection to use for executing the script

reader - the source of the script

Throws:

NullPointerException - if the reader is null

runScriptFromResourceFile

public static void runScriptFromResourceFile(Connection connection,
                                             String resourcePath)

runCommands

public static void runCommands(Connection connection,
                               List<String> commands)

readSQLCommandsAsString

public String readSQLCommandsAsString(Reader reader)

Parameters:

reader - for SQL script

Returns:

extract SQL commands

readCommands

public List<String> readCommands(Reader reader)

execInsert

public static InsertionResultsDto execInsert(Connection conn,
                                             List<InsertionDto> insertions,
                                             InsertionResultsDto... previous)
                                      throws SQLException

Execute the different SQL insertions. These can refer to each other via foreign keys, even in the case of auto-generated IDs.

Parameters:

conn - a JDBC connection to the database

insertions - the SQL insertions to execute

previous - the results of previously executed SQL insertions

Returns:

a map from InsertionDto ID to ID of auto-generated primary keys in the database (if any were generated). If an InsertionDto has no ID, we will not keep track of any auto-generated value for it.

Throws:

SQLException - if a database access error occurs

execInsert

public static Long execInsert(Connection conn,
                              String command)
                       throws SQLException

Executes the given SQL insertion command.

Parameters:

conn - a JDBC connection to the database

command - the SQL insertion to execute

Returns:

a single ID for the new row, if any was automatically generated, null otherwise. In other words, returns the value of the auto-generated primary key, if any was created.

Throws:

SQLException - if a database access error occurs

execScript

public static void execScript(Connection conn,
                              String script)
                       throws SQLException

this is used for mysql which cannot execute multiple statements at one time.

Parameters:

conn - a connection to db

script - represents a sql script

Throws:

SQLException - if the execution of the command fails

execScript

public static void execScript(Connection conn,
                              String script,
                              List<String> tablesToInsert)
                       throws SQLException

Parameters:

conn - a connection to db

script - represents a sql script

tablesToInsert - represents insertions are executed only on the tables in this list. insertions for other tables will be skipped. if it is null or empty, nothing will be inserted.

public static List<String> extractSql(String script)

Parameters:

script - is a SQL script

Returns:

a list of SQL commands based on the script

extractSqlTableMap

Parameters:

commands - a list of SQL commands to be extracted

Returns:

the map from table name (key) to a list of SQL INSERT commands (values) on the table

execCommand

public static QueryResult execCommand(Connection conn,
                                      String command)
                               throws SQLException
