Method Summary

Modifier and Type	Method	Description
static java.lang.String	getTzColumnNames(java.util.List<Column> columns, Column col)	Creates a description for a TzColumn to tie a DateTime column to its Tz col, which could be a unique column, or a shared row col based on tzMode.
static java.lang.String	getTzColumnNames(java.util.List<ViewColumn> columns, ViewColumn col)	Creates a description for a TzColumn to tie a DateTime column to its Tz col, which could be a unique column, or a shared row col based on tzMode. For views, this is a bit more complicated as multiple row-level rowTz columns may be imported from multiple source views/tables, and be further modified by aggregates and order-by clauses.
static java.lang.String	getTzName(java.lang.String colName, Column sameAsObj, AggregateType agg, java.lang.String[] orderBys, boolean sameAs)	Returns the name of the associated TZ column for this column.

Method Detail

getTzName

public static java.lang.String getTzName(java.lang.String colName,
                                         Column sameAsObj,
                                         AggregateType agg,
                                         java.lang.String[] orderBys,
                                         boolean sameAs)

Returns the name of the associated TZ column for this column. This should be called only if "needsTZ" returns true. For row columns, will rename the rowTZ based on the source table/view, or aggregate. For example:

• sameAs="SomeTable1.DateTimeColumnWithRowTZ"
• sameAs="SomeTable2.DateTimeColumnWithRowTZ"
• sameAs="SomeTable1.DateTimeColumn1WithRowTZ", aggregate="FIRST", orderBy:["dt1"]
• sameAs="SomeTable1.DateTimeColumn2WithRowTZ", aggregate="FIRST", orderBy:["dt2"]

We need to make sure that in the resulting view has 4 instances of rowTZ because:

• The first two come from 2 different tables, so their rowTZ might be different
• The last 2 have a different orderBy, and so the matching rowTZ might again be different.

Parameters:

sameAs -

Returns:

getTzColumnNames

public static java.lang.String getTzColumnNames(java.util.List<Column> columns,
                                                Column col)

Creates a description for a TzColumn to tie a DateTime column to its Tz col, which could be a unique column, or a shared row col based on tzMode.

Parameters:

columns -

col -

Returns:

getTzColumnNames

public static java.lang.String getTzColumnNames(java.util.List<ViewColumn> columns,
                                                ViewColumn col)

Creates a description for a TzColumn to tie a DateTime column to its Tz col, which could be a unique column, or a shared row col based on tzMode.
For views, this is a bit more complicated as multiple row-level rowTz columns may be imported from multiple source views/tables, and be further modified by aggregates and order-by clauses.

Parameters:
