The GlideSysAttachment API provides methods for handling attachments.

Content is returned as a GlideScriptableInputStream object when getContentStream() is called. The GlideScriptableInputStream contains the actual bytes not converted into a string.

## GlideSysAttachment - GlideSysAttachment() {#ariaid-title2}

Creates an instance of the GlideSysAttachment class.
{#GSA-GlideSysAttachment__table_iys_ctb_fv__entry__3}

| Name | Type | Description |
|-|-|-|
| None |   |   |
[Table 1. Parameters]

{#GSA-GlideSysAttachment__table_iys_ctb_fv}

## GlideSysAttachment - copy(String sourceTable, String sourceID, String targetTable, String targetID) {#ariaid-title3}

Copies attachments from the source record to the target record.
{#GSA-copy_S_S_S_S__id_g4d_yjz_g5b__entry__3}

| Name | Type | Description |
|-|-|-|
| sourceTable | String | Name of the table with the attachments to be copied. |
| sourceID | String | Source table's sys_id. |
| targetTable | String | Name of the table on which to add the attachments. |
| targetID | String | Target table's sys_id. |
[Table 2. Parameters]

{#GSA-copy_S_S_S_S__id_g4d_yjz_g5b} {#GSA-copy_S_S_S_S__id_afm_yjz_g5b__entry__2}

| Type | Description |
|-|-|
| String | Array of sys_ids of the attachments that were copied. |
[Table 3. Returns]

{#GSA-copy_S_S_S_S__id_afm_yjz_g5b}  

    var attachment = new GlideSysAttachment();
    var incidentSysID = 'ab1b30031b04ec101363ff37dc4bcbfc';
    var incGR = new GlideRecord('incident');
    incGR.get(incidentSysID);

    var copiedAttachments = attachment.copy('incident', incidentSysID, 'problem', incGR.getValue('problem_id'));
    gs.info('Copied attachments: ' + copiedAttachments);

Output:

    Copied attachments: 6e4621df1bc420501363ff37dc4bcbb0,a87769531b0820501363ff37dc4bcba2

## GlideSysAttachment - deleteAttachment(String attachmentID) {#ariaid-title4}

Deletes the specified attachment.
{#GSA-deleteAttachment_S__id_ywb_ykz_g5b__entry__3}

| Name | Type | Description |
|-|-|-|
| attachmentID | String | Attachment's sys_id. |
[Table 4. Parameters]

{#GSA-deleteAttachment_S__id_ywb_ykz_g5b} {#GSA-deleteAttachment_S__table_gjy_lyb_fv__entry__2}

    var attachmentSysID = 'a87769531b0820501363ff37dc4bcba2';
    attachment.deleteAttachment(attachmentSysID);

## GlideSysAttachment - getAttachments(String tableName, String sys_id) {#ariaid-title5}
