Class MsSequence

All Implemented Interfaces:
IRelation, ISearchPath, ISequence, IStatement, IHashable

public class MsSequence extends MsAbstractStatement implements ISequence
Represents a Microsoft SQL sequence object. Sequences generate sequential numeric values and are commonly used for primary keys and unique identifiers.

    • MsSequence

      public MsSequence(String name)
      Creates a new Microsoft SQL sequence with BIGINT data type as default.
      Parameters:
      name - the sequence name
  • Method Details

    • getCreationSQL

      public void getCreationSQL(SQLScript script)
      Description copied from interface: IStatement
      Generates the SQL statements needed to create this database object. This is an abstract method that must be implemented by subclasses to provide the specific CREATE SQL for each object type.
      Specified by:
      getCreationSQL in interface IStatement
      Parameters:
      script - the SQL script to append creation statements to
    • appendAlterSQL

      public ObjectState appendAlterSQL(IStatement newCondition, SQLScript script)
      Description copied from interface: IStatement
      Fill script with object changes and return change type
      Specified by:
      appendAlterSQL in interface IStatement
      Parameters:
      newCondition - new object state
      script - script to collect changes
      Returns:
      object change type
    • setDataType

      public void setDataType(String dataType)
    • setMinMaxInc

      public void setMinMaxInc(long inc, Long max, Long min, String dataType, long precision)
    • setCached

      public void setCached(boolean isCached)
    • setStartWith

      public void setStartWith(String startWith)
    • setCycle

      public void setCycle(boolean cycle)
    • setCache

      public void setCache(String cache)
    • getRelationColumns

      public Stream<Pair<String,String>> getRelationColumns()
      Description copied from interface: IRelation
      Gets the columns of this relation as name-type pairs.
      Specified by:
      getRelationColumns in interface IRelation
      Returns:
      a stream of column name and type pairs
    • computeHash

      public void computeHash(Hasher hasher)
      Description copied from interface: IHashable
      Computes the hash of the implementing object using the provided hasher. The implementation should call appropriate put methods on the hasher for all fields that should contribute to the hash value.
      Specified by:
      computeHash in interface IHashable
      Parameters:
      hasher - the hasher instance to use for hash computation
    • compare

      public boolean compare(IStatement obj)
      Description copied from class: AbstractStatement
      This method does not account for nested child PgStatements. Shallow version of AbstractStatement.equals(Object)
      Specified by:
      compare in interface IStatement
      Overrides:
      compare in class AbstractStatement
