public class FoxProDictionary
extends DBDictionary

Dictionary for Visual FoxPro via DataDirect SequeLink and DataDirect ODBC FoxPro driver. This will not work with any other combination of JDBC/ODBC server and ODBC driver. FoxPro has the following limitations:

• Primary Keys and indexes cannot be created via JDBC
• Only has fixed-length char fields: all strings must be trimmed in result sets
• Does not have sufficient support for foreign keys
• ODBC driver cannot handle certain Aggregate functions.
• Locking is extremeley unreliable. Multiple clients accessing single datastore may result in concurrency data validity errors.

Method Details

getString

public String getString(ResultSet rs,
 int column)
                 throws SQLException

Description copied from class: DBDictionary

Convert the specified column of the SQL ResultSet to the proper java type.

Overrides:

getString in class DBDictionary

Throws:

SQLException

setNull

public void setNull(PreparedStatement stmnt,
 int idx,
 int colType,
 Column col)
             throws SQLException

Description copied from class: DBDictionary

Set null as a parameter to the statement. The column type will come from Types.

Overrides:

setNull in class DBDictionary

Throws:

SQLException

appendSize

protected String appendSize(Column col,
 String typeName)

Description copied from class: DBDictionary

Helper method to add size properties to the specified type. If present, the string "{0}" will be replaced with the size definition; otherwise the size definition will be appended to the type name. If your database has column types that don't allow size definitions, override this method to return the unaltered type name for columns of those types (or add the type names to the fixedSizeTypeNameSet).

Some databases support "type modifiers", for example the unsigned "modifier" in MySQL. In these cases the size should go between the type and the "modifier", instead of after the modifier. For example CREATE table FOO ( myint INT (10) UNSIGNED . . .) instead of CREATE table FOO ( myint INT UNSIGNED (10) . . .). Type modifiers should be added to typeModifierSet in subclasses.

Overrides:

appendSize in class DBDictionary

getPrimaryKeyConstraintSQL

protected String getPrimaryKeyConstraintSQL(PrimaryKey pk)

Overrides:

getCreateIndexSQL

public String[] getCreateIndexSQL(Index index)

Description copied from class: DBDictionary

Return a series of SQL statements to create the given index. Returns CREATE [UNIQUE] INDEX <index name> ON <table name> (<col list>) by default.
