Searching the Help
To search for information in the Help, type a word or phrase in the Search box. When you enter a group of words, OR is inferred. You can use Boolean operators to refine your search.
Results returned are case insensitive. However, results ranking takes case into account and assigns higher scores to case matches. Therefore, a search for "cats" followed by a search for "Cats" would return the same number of Help topics, but the order in which the topics are listed would be different.
Words and Phrases
| Search for | Example | Results |
|---|---|---|
| A single word | cat
|
Topics that contain the word "cat". You will also find its grammatical variations, such as "cats". |
|
A phrase. You can specify that the search results contain a specific phrase. |
"cat food" (quotation marks) |
Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase. |
Using Boolean Operators
| Search for | Operator | Example |
|---|---|---|
|
Two or more words in the same topic |
|
|
| Either word in a topic |
|
|
| Topics that do not contain a specific word or phrase |
|
|
| Topics that contain one string and do not contain another | ^ (caret) |
cat ^ mouse
|
| A combination of search types | ( ) parentheses |

Field in main table
The field in main table format maps a Service Manager array field as a character large object (CLOB) within a main table. This array format is good for situations where the following conditions apply:
- You want to be able to use third-party tools to run reports against your array data
- You want the option to store very large array elements
- You do not want to remap an existing array
The following table summarize the advantages of using this array mapping format.
| Advantage | Description |
|---|---|
| Third-party tools can report against the array | Service Manager stores array data as a character string that third-party reporting tools can read. The system separates each element of the array with a \n character delimiter. |
| The array can store very large array elements | Since the array is mapped to a character large object column, the column can occupy a large amount of space. Most RDBMS vendors support at least 2 gigabytes of large object data in such a column. |
| The array has access to other fields in the main table | There is a greater probability that other fields reside in the same main table as the array. Having all or most of your fields in a main table reduces the number of SELECT and JOIN statements your system has to make to fetch a record. The less RDBMS traffic required, the better performance your queries and reports will have. |
| There is no need to remap if you use the default array mapping format | The field in main table format is Service Manager's out-of-box array mapping format. Unless someone has changed the default array mapping format, all your array data will automatically be in this format. |
The following table summarize the disadvantages of using this array mapping format.
| Disadvantage | Description |
|---|---|
| The RDBMS cannot directly query the array | Most RDBMS vendors cannot query a column containing a reference to character large object data. |
| Any query against the array is inefficient | The RDBMS cannot directly query this array format because the column is mapped to a large object data type. Instead, the RDBMS must scan the table to return all rows of the large object column, and then forward the results to Service Manager for evaluation. |
| The array shares table space with other fields in the table | The array does not have a dedicated table in which to store data. Each RDBMS vendor has its own rules to determine the maximum number of columns allowed in a table, the maximum size of any row, and the maximum table size. Any array in a main table will consume some of these RDBMS resources. If an array requires more resources than any one main table can provide, Service Managerwill move the array to another main table. |
To set up an array in a field in main table mapping, you must create the following mappings in a database dictionary record.
| Database dictionary element type | RDBMS mapping required |
|---|---|
| Array data type | Not mapped |
| Sub-field of the array | Mapped as a CLOB column in a main table |
| RC flag | False |
