public int getType()
Returns the columnIter java.sql.Type enun of the column.


getTypeName

public java.lang.String getTypeName()
Returns the columnIter java.sql.Type name.


getTable

public JdbcSchema.Table getTable()
Returns this column's table.


getDatatype

public Dialect.Datatype getDatatype()
Return true if this column is numeric.


getColumnSize

public int getColumnSize()
Returns the size in bytes of the column in the database.


getDecimalDigits

public int getDecimalDigits()
Returns number of fractional digits.


getNumPrecRadix

public int getNumPrecRadix()
Returns Radix (typically either 10 or 2).


getCharOctetLength

public int getCharOctetLength()
For char types the maximum number of bytes in the column.


isNullable

public boolean isNullable()
False means the column definitely does not allow NULL values.


numberOfUsages

public int numberOfUsages()
How many usages does this column have. A column has between 0 and N usages. It has no usages if usages is some administrative column. It has one usage if, for example, its the fact_count column or a level column (for a collapsed dimension aggregate). It might have 2 usages if its a foreign key that is also used as a measure. If its a column used in N measures, then usages will have N usages.


hasUsage

public boolean hasUsage()
Return true if the column has at least one usage.


hasUsage

public boolean hasUsage(JdbcSchema.UsageType columnType)
Return true if the column has at least one usage of the given column type.


getUsages

public java.util.List<JdbcSchema.Table.Column.Usage> getUsages()
Returns an iterator over all usages.


getUsages

public java.util.Iterator<JdbcSchema.Table.Column.Usage> getUsages(JdbcSchema.UsageType usageType)
Returns an iterator over all usages of the given column type.


newUsage

public JdbcSchema.Table.Column.Usage newUsage(JdbcSchema.UsageType usageType)
Create a new usage of a given column type.


toString

public java.lang.String toString()
Overrides:
toString in class java.lang.Object
