Data Transformation
Data transformation operations use functions and expressions to functionally alter tabular data. These operations take 0, 1, or 2 tables as input and produce a single table as a result.
<colord>
<colord> tells the system which columns to display and in what order.

- Data Transformation
  Data transformation operations use functions and expressions to functionally alter tabular data. These operations take 0, 1, or 2 tables as input and produce a single table as a result.
  - <amend>
    Update a specified value, or column of values, either by entering a new value or by using an expression. The expression can be applied to the column the value is in or to another column.
  - <base>
    <base> is the concrete macro operation that represents the action of opening the initial table.
  - <col>
    <col> changes the display attributes of a column in a table. It does not change the name of a column, but it does change the heading, as an example.
  - <colord>
    <colord> tells the system which columns to display and in what order.
  - <cols>
    Modifies the metadata of multiple columns at once, based on a query result or formatted tabular input.
  - <columns>
    <columns> is a special operation that retrieves column information from a table.
  - <directory>
    <directory> returns a table that provides information about the child objects of a particular folder. These include any tables, folders, and queries that have been saved to that folder.
  - <find>
    Efficiently finds (without selecting) the first n rows, between the specified row numbers, where the specified Boolean value expression is true.
  - <ignore>
    <ignore> encases code in a Macro Language query that should not be executed by the system.
  - <link>
    Link a foreign table to a base table or worksheet. Both tables must share a column on which to link.
  - <materialize>
    Creates a new physical table.
  - <merge>
    Merge a table to another table or worksheet.
  - <meta>
    <meta> allows settings to be made at the level of an individual query (and saved along with the query).
  - <note>
    <note> may be used to place a comment in the Macro Language. The contents of the element is any standard text.
  - <sel>
    Select the rows relevant to your analysis.
  - <sort>
    Changes the order in which rows appear in a table by sorting according to the values in a column.
  - <stats:>
    The <stats:> package provides more advanced statistics operations.
  - <table>
    <table> is a special operation that creates a temporary table within the scope of a query.
  - <tabu>
    <tabu> defines a tabulation or cross-tabulation.
  - <transpose>
    <transpose> results in a table in which the rows from the original table are its columns and the columns from the original table are its rows.
  - <willbe>
    Define a new computed column in an existing worksheet with a value expression.
- Blocks
  Blocks allow users to reuse sections of Macro Language code and to parameterize values in that code for greater flexibility and power.
- Application Development

`<colord>`

<colord> tells the system which columns to display and in what order.

Syntax

<colord cols="[COL_NAME_1,COL_NAME_2,...COL_NAME_N]" hide="[HIDE_COL_1,HIDE_COL_2,...HIDE_COL_N]"/>

Attributes

cols

A comma-separated list of column names (real or computed) to be displayed.

This is the set of all columns that may be displayed via scrolling and may include more columns than can be displayed at any one time.

If omitted, all columns are selected (except those specified in the hide attribute, if present).

You can use the * character as a wild card when you specify column names. For instance, <colord cols="c*"/> displays only those columns that begin with the letter c.

hide

A comma-separated list of column names (real or computed) to be hidden.

If omitted, all columns specified in the cols attribute (if present) are displayed; if cols is absent, all available columns are displayed.

You can use the * character as a wild card when you specify column names. For instance, <colord hide="c*"/> hides those columns that begin with the letter c.

hard

Accepts an integer value of 0 or 1 that specifies whether or not the worksheet’s hidden columns can be referenced or unhidden in any subsequent Macro Language code in the query.

When hard="1", hidden columns cannot be referenced or unhidden in subsequent Macro Language code in the query.

The default is 0.

Note: If a column is present in both the cols and hide lists, it will not be displayed (i.e., hide takes priority over cols). If a column specified in either attribute does not exist, it is ignored.

Example

<base table="pub.demo.retail.item"/>
<colord cols="date, transid, sku, store, sales, cost"/>

Example: Using the hard attribute

The following example shows that after specifying hard="1" in the <colord> operation, the sku column cannot be made visible by a subsequent <colord>.

<base table="pub.demo.retail.item"/>
<colord cols="date,store,sku"/>
<colord cols="date,store" hard="1"/>
<colord cols="date,store,sku"/>

Contrast this with the same code without the hard="1" attribute:

<base table="pub.demo.retail.item"/>
<colord cols="date,store,sku"/>
<colord cols="date,store"/>
<colord cols="date,store,sku"/>
