Constructor Detail

PostgreSqlInsertWriter

public PostgreSqlInsertWriter(String tableName,
                              File file,
                              boolean append)

PostgreSqlInsertWriter

public PostgreSqlInsertWriter(String tableName,
                              File file)

PostgreSqlInsertWriter

public PostgreSqlInsertWriter(String tableName,
                              Writer writer)

Method Detail

writeRecord

protected void writeRecord(Record record)
                    throws Throwable

Specified by:

writeRecord in class AbstractWriter

Throws:

Throwable

close

public void close()

Description copied from class: DataEndpoint

Indicates that this endpoint has finished reading or writing.

Overrides:

close in class TextWriter

getTableName

public String getTableName()

isPretty

public boolean isPretty()

setPretty

public PostgreSqlInsertWriter setPretty(boolean pretty)

Indicates if line breaks and indentations should be added to output insert statement (default false).

Example output (pretty = true):
INSERT INTO "tableName" ("col1", "col2", "col3")
VALUES (val1, val2, val3),

       (val1, val2, val3),

       (val1, val2, val3),...

Example output (pretty = false):
INSERT INTO "tableName" ("col1", "col2", "col3") VALUES (val1, val2, val3), (val1, val2, val3), (val1, val2, val3),...

getBatchSize

public int getBatchSize()

setBatchSize

public PostgreSqlInsertWriter setBatchSize(int batchSize)

Sets the number of records to chunk together in batch inserts. Inserts are not batched if this value is 1 or less. PostgreSqlInsertWriter defaults to non batching inserts.

Example output (batchSize = 2):
INSERT INTO "tableName" ("col1", "col2", "col3")
VALUES (val1, val2, val3),

       (val1, val2, val3);

Example output (batchSize = 0):
INSERT INTO "tableName" ("col1", "col2", "col3") VALUES (val1, val2, val3);
INSERT INTO "tableName" ("col1", "col2", "col3") VALUES (val1, val2, val3);

isBatchMode

protected boolean isBatchMode()

setFieldNamesInFirstRow

public PostgreSqlInsertWriter setFieldNamesInFirstRow(boolean fieldNamesInFirstRow)

Overrides:

setFieldNamesInFirstRow in class AbstractWriter

addExceptionProperties

public DataException addExceptionProperties(DataException exception)

Description copied from class: Endpoint

Adds this endpoint's current state to a DataException. Since this method is called whenever an exception is thrown, subclasses should override it to add their specific information.

Overrides:

addExceptionProperties in class TextWriter

getSqlValueLiteral

protected String getSqlValueLiteral(Field field)
