Updating dictionary

If the spell checker flags certain words as misspelled but you want it to ignore these words, you can add them to the default custom dictionary.(To change the default custom dictionary where these words are added, see Change the custom dictionary to which the spelling checker adds words).

To access dictionary elements, you can use the familiar square brackets along with the key to obtain its value.

Following is a simple example − You can either remove individual dictionary elements or clear the entire contents of a dictionary.

When you add words while checking spelling, new words are added to the default custom dictionary, which is the one at the top of the list when you open the Custom Dictionaries dialog box.

You can change the default custom dictionary used for all Office programs: By default, when you create a new custom dictionary, the program sets the dictionary to All Languages, which means that the dictionary is used when you check the spelling of text in any language.

Each key is separated from its value by a colon (:), the items are separated by commas, and the whole thing is enclosed in curly braces.

An empty dictionary without any items is written with just two curly braces, like this: .(An Amazon Redshift disk block occupies 1 MB.) The dictionary contains up to 256 one-byte values that are stored as indexes to the original data values.If more than 256 values are stored in a single block, the extra values are written into the block in raw, uncompressed form. This encoding is very effective when a column contains a limited number of unique values.If you will not use all of the rows in the staging table, you can filter the DELETE and INSERT statements by using a WHERE clause to leave out rows that are not actually changing.However, if most of the rows in the staging table will not participate in the merge, we recommend performing an UPDATE and an INSERT in separate steps, as described later in this section., command to update a table from a single data source, you can perform a merge operation by creating a staging table and then using one of the methods described in this section to update the target table from the staging table.
