Method Detail

encode

protected String encode(String s)

Description copied from class: Db

e.g. in H2, STRINGENCODE('abc\ndef') will convert the String such that steering characters are interpreted correctly; default: no encoding

Overrides:

encode in class Db

Returns:

mapDataType

protected String mapDataType(String originalDataType)

Description copied from class: Db

when copying a table to this connection, the original data type (copied from an other connection with maybe a different DB system) can be mapped to an other datatype. E.g., you would transform a BOOLEAN from Postgres to a bit on MS-SQL

Overrides:

mapDataType in class Db

Returns:

mapped type

mapValue

protected Object mapValue(Object o)

Description copied from class: Db

maps value if necessary; e.g. time like values can be converted to strings; binary values can be mapped to hex strings prefixed by some 0x or whatever the DB likes to hear in this case

Overrides:

mapValue in class Db

Returns:

beginTransactionStatement

protected String beginTransactionStatement()

Overrides:

beginTransactionStatement in class Db

quoteIdentifierIfNecessary

protected String quoteIdentifierIfNecessary(String unquotedTableName)

Description copied from class: Db

if some circumstances, table and column names themselves have to be quoted, e.g. to deal with upper/lower case problems, this is done here

Overrides:

quoteIdentifierIfNecessary in class Db

Returns:

e.g. makes "\"MYTABLE\"" from "MYTABLE"
