    • Method Detail

      • buildClassTypes

        protected java.util.Map<java.lang.String,​java.lang.Class> buildClassTypes()
        Description copied from class: DatabasePlatform
        Return the mapping of class types to database types for the schema framework.
        Overrides:
        buildClassTypes in class DatabasePlatform

      • buildFieldTypes

        protected java.util.Hashtable buildFieldTypes()
        Description copied from class: DatabasePlatform
        Return the mapping of class types to database types for the schema framework.
        Overrides:
        buildFieldTypes in class DatabasePlatform

      • getMaxFieldNameSize

        public int getMaxFieldNameSize()
        INTERNAL: returns the maximum number of characters that can be used in a field name on this platform.
        Overrides:
        getMaxFieldNameSize in class DatabasePlatform

      • maximumNumericValues

        public java.util.Hashtable maximumNumericValues()
        Builds a table of maximum numeric values keyed on java class. This is used for type testing but might also be useful to end users attempting to sanitize values.

        NOTE: BigInteger & BigDecimal maximums are dependent upon their precision & Scale

        Overrides:
        maximumNumericValues in class DatabasePlatform

      • minimumNumericValues

        public java.util.Hashtable minimumNumericValues()
        Builds a table of minimum numeric values keyed on java class. This is used for type testing but might also be useful to end users attempting to sanitize values.

        NOTE: BigInteger & BigDecimal minimums are dependent upon their precision & Scale

        Overrides:
        minimumNumericValues in class DatabasePlatform

      • requiresNamedPrimaryKeyConstraints

        public boolean requiresNamedPrimaryKeyConstraints()
        This is used as some databases create the primary key constraint differently, i.e. Access.
        Overrides:
        requiresNamedPrimaryKeyConstraints in class DatabasePlatform

      • shouldUseJDBCOuterJoinSyntax

        public boolean shouldUseJDBCOuterJoinSyntax()
        JDBC defines and outer join syntax, many drivers do not support this. So we normally avoid it.
        Overrides:
        shouldUseJDBCOuterJoinSyntax in class DatabasePlatform

      • supportsIdentity

        public boolean supportsIdentity()
        INTERNAL: Indicates whether the platform supports identity. Sybase does through IDENTITY field types. This method is to be used *ONLY* by sequencing classes
        Overrides:
        supportsIdentity in class DatasourcePlatform

      • printFieldUnique

        public void printFieldUnique​(java.io.Writer writer,
                             boolean shouldPrintFieldIdentityClause)
                      throws java.io.IOException
        Overrides:
        printFieldUnique in class DatabasePlatform
        Throws:
        java.io.IOException
