# GlideRecordUtil- Global

The GlideRecordUtil script include is a utility class for working with GlideRecords.

This script include is available in server-side scripts. For use cases, see [Using discovery script includes](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/scripts/c_ScriptIncludes.md).

**Parent Topic:**[Server API reference](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/server-api-reference/api-server.md)

## GlideRecordUtil - getCIGR\(String sys\_id\)

Returns the GlideRecord object for the specified configuration item \(CI\) using just the sys\_id of the CI.

Use this method to quickly obtain a specific CI without knowing its associated class/table.

|Name|Type|Description|
|----|----|-----------|
|sys\_id|String|Sys\_id of the desired CI.|

|Type|Description|
|----|-----------|
|[GlideRecord](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/server-api-reference/c_GlideRecordAPI.md)|GlideRecord object of the specified CI.|

The following example returns the GlideRecord object for the specified CI using just the sys\_id of the CI.

```
var now_GR = new GlideRecordUtil().getCIGR("2dfd7c8437201000deeabfc8bcbe5d56");
```

## GlideRecordUtil - getFields\(GlideRecord gr\)

Returns an array of all the fields in the specified GlideRecord.

**Note:** If there is a field name which is the same as the table name, the getFields\(\) method does not return the value of the field.

|Name|Type|Description|
|----|----|-----------|
|gr|[GlideRecord](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/server-api-reference/c_GlideRecordAPI.md)|GlideRecord instance positioned to a valid record.|

|Type|Description|
|----|-----------|
|Array|Field names for the specified GlideRecord.|

```
var queryString = "priority=1^ORpriority=2";
var now_GR = new GlideRecord('incident');
now_GR.addEncodedQuery(queryString);
now_GR.query();
now_GR.next();

var gRU = new GlideRecordUtil();
var fieldList = gRU.getFields(now_GR);
gs.info(fieldList);
```

Output: Line breaks added for presentation.

```

## GlideRecordUtil - getGR\(String baseTable, String sys\_id\)

Returns a GlideRecord instance for the given table, positioned to the given sys\_id, and of the right class \(table\).

This method is useful when you need to load a GlideRecord from a sys\_id, but you don't know what the actual table is \(because it may be extended from the base table\). This method always returns a GlideRecord of the correct type base\_table: the name of the base table that the specified sys\_id is in.

|Name|Type|Description|
|----|----|-----------|
|baseTable|String|The name of the base table containing the sys\_id.|
|sys\_id|String|The sys\_id of the desired record.|

|Type|Description|
|----|-----------|
|[GlideRecord](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/server-api-reference/c_GlideRecordAPI.md)|The GlideRecord for the specified sys\_id.|

```
var now_GR = new GlideRecordUtil().getGR("cmdb_ci_computer", "2dfd7c8437201000deeabfc8bcbe5d56");
```

## GlideRecordUtil - getTables\(String tableName\)

Returns a list of the ancestors of a specified table.

**Note:** The specified table is included in the list of its ancestors.

|Name|Type|Description|
|----|----|-----------|
|tableName|String|Name of the table.|

|Type|Description|
|----|-----------|
|Array|List of ancestors of the specified table.|

The following example shows the ancestors of the Linux Server \[cmdb\_ci\_linux\_server\] table.

```
var tables = new GlideRecordUtil().getTables("cmdb_ci_linux_server");
gs.info("Tables returned: " + tables);
```

Output:

```
Tables returned: [cmdb_ci_linux_server, cmdb_ci_server, cmdb_ci_computer, cmdb_ci_hardware, cmdb_ci, cmdb]

```

## GlideRecordUtil - mergeToGR\(Object hashMap, GlideRecord now\_GR, Object ignore\)

Sets the fields in the specified GlideRecord with the field values contained in the specified hashmap, unless that field name is in the ignore hashmap.

|Name|Type|Description|
|----|----|-----------|
|hashMap|Object|An Object instance \(being used as a hashmap\), with properties named for fields and containing the fields' value.|
|now\_GR|[GlideRecord](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/server-api-reference/c_GlideRecordAPI.md)|The GlideRecord instance to receive the field values.|
|ignore|Object|An optional hashmap of field names to ignore.|

|Type|Description|
|----|-----------|
|void| |

This example updates a computer record's name and os fields, but does not update the sys\_created\_by field:

```
var now_GR = new GlideRecordUtil().getGR("cmdb_ci_computer", "2dfd7c8437201000deeabfc8bcbe5d56");   
var obj = {"name": "xyz", "os": "windows 2000", "sys_created_by", "aleck.lin"};
var ignore = {"sys_created_by": true};
new GlideRecordUtil().mergeToGR(obj, now_GR, ignore);
now_GR.update();
```

## GlideRecordUtil - populateFromGR\(Object hashMap, GlideRecord now\_GR, Object ignore\)

Populates a given hashmap from a GlideRecord. Each field in the GlideRecord becomes a property in the hashmap.

<table id="table_czg_4lw_4t" class="parameters"><thead><tr><th>

Name

</th><th>

Type

</th><th>

Description

</th></tr></thead><tbody><tr><td>

[GlideRecord](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/api-reference/server-api-reference/c_GlideRecordAPI.md)

</td><td>

</td></tr><tr><td>

</td><td>

</td><td>

Optional. A hashmap of field names to exclude when populating the object.For each key-value pair in the map, the key is the name of the field to exclude and the value is `true`.

```
{"field_name": true}
```

</td></tr></tbody>
</table>|Type|Description|
|----|-----------|
|void| |

This example populates an object with fields and values from a Computer \[cmdb\_ci\_computer\] record.

```
var util = new GlideRecordUtil();
var objectToPopulate = {};
var computer = util.getCIGR("2dfd7c8437201000deeabfc8bcbe5d56"); // get CI record from cmdb_ci_computer
var ignore = {"sys_created_on": true, "sys_updated_by": true};
util.populateFromGR(objectToPopulate, computer, ignore);
// Now objectToPopulate contains field/value pairs from the computer GlideRecord
gs.info(JSON.stringify(objectToPopulate));
```

Output:
