AdsApp.​SnippetSelector

Fetches snippets. Supports filtering and sorting.

Typical usage:

 var snippetSelector = AdsApp.extensions()
     .snippets()
     .withCondition("Impressions > 100")
     .forDateRange("LAST_MONTH")
     .orderBy("Clicks DESC");

 var snippetIterator = snippetSelector.get();
 while (snippetIterator.hasNext()) {
   var snippet = snippetIterator.next();
 }

Methods:

Member	Type	Description
forDateRange	AdsApp.SnippetSelector	Sets a predefined date range onto the selector.
forDateRange	AdsApp.SnippetSelector	Sets a custom date range onto the selector.
get	AdsApp.SnippetIterator	Fetches the requested snippets and returns an iterator.
orderBy	AdsApp.SnippetSelector	Specifies the ordering of the resulting entities.
withCondition	AdsApp.SnippetSelector	Adds the specified condition to the selector in order to narrow down the results.
withIds	AdsApp.SnippetSelector	Restricts this selector to return only snippets with the given snippet IDs.
withLimit	AdsApp.SnippetSelector	Specifies limit for the selector to use.

forDateRange(dateRange)

Sets a predefined date range onto the selector. Supported values:

TODAY, YESTERDAY, LAST_7_DAYS, THIS_WEEK_SUN_TODAY, LAST_WEEK, LAST_14_DAYS, LAST_30_DAYS, LAST_BUSINESS_WEEK, LAST_WEEK_SUN_SAT, THIS_MONTH, LAST_MONTH, ALL_TIME. Example:

 selector.forDateRange("THIS_WEEK_SUN_TODAY");

Date range must be specified if the selector has conditions or ordering for a stat field. Note that only the last date range specified for the selector will take effect.

Arguments:

Name	Type	Description
dateRange	String	Date range to set onto the selector.

Return values:

Type	Description
AdsApp.SnippetSelector	The selector with date range applied.

forDateRange(dateFrom, dateTo)

Sets a custom date range onto the selector. Both parameters can be either an object containing year, month, and day fields, or an 8-digit string in YYYYMMDD form. For instance, March 24th, 2013 is represented as either {year: 2013, month: 3, day: 24} or "20130324". The date range is inclusive on both ends, so forDateRange("20130324", "20130324") sets the range of one day.

Date range must be specified if the selector has conditions or ordering for a stat field. Note that only the last date range specified for the selector will take effect.

Arguments:

Name	Type	Description
dateFrom	Object	Start date of the date range.
dateTo	Object	End date of the date range.

Return values:

Type	Description
AdsApp.SnippetSelector	The selector with date range applied.

get()

Fetches the requested snippets and returns an iterator.

Return values:

Type	Description
AdsApp.SnippetIterator	Iterator of the requested snippets.

orderBy(orderBy)

Specifies the ordering of the resulting entities. orderBy parameter can have one of the following forms:

• orderBy("Cost") - orders results by Cost, in ascending order.
• orderBy("Ctr ASC") - orders results by Ctr, in ascending order.
• orderBy("MaxCpc DESC") - orders results by MaxCpc, in descending order.

See SnippetSelector.withCondition(String) for enumeration of columns that can be used.

orderBy() may be called multiple times. Consider the following example:

 selector = selector.forDateRange("LAST_14_DAYS")
     .orderBy("Clicks DESC")
     .orderBy("CTR ASC");

The results will be ordered by Clicks in descending order. Results with equal Clicks value will be ordered by Ctr in ascending order.

If a stats column is used in the ordering, date range must be specified via SnippetSelector.forDateRange(String) or SnippetSelector.forDateRange(Object, Object).

LabelNames column cannot be used for ordering.

Arguments:

Name	Type	Description
orderBy	String	Ordering to apply.

Return values:

Type	Description
AdsApp.SnippetSelector	The selector with ordering applied.

withCondition(condition)

Adds the specified condition to the selector in order to narrow down the results.

Multiple conditions may be added to the same selector:

 selector = selector.forDateRange("LAST_MONTH")
     .withCondition("Clicks > 5")
     .withCondition("Impressions > 100");

All specified conditions are AND-ed together. The above example will retrieve entities that observed over 100 impressions AND more than 5 clicks.

The parameter to be passed into this method must be of the following form:

 "COLUMN_NAME OPERATOR VALUE"

Operators

The operator that can be used in a condition depends on the type of column.

• For Integer and Long columns (e.g. Impressions, Clicks):

  <  <=  >  >=  =  !=

• For Double columns (e.g. Ctr, AveragePosition):

  <  >

• For String columns (e.g. Name):

  =  !=  STARTS_WITH  STARTS_WITH_IGNORE_CASE  CONTAINS
   CONTAINS_IGNORE_CASE  DOES_NOT_CONTAIN  DOES_NOT_CONTAIN_IGNORE_CASE

• For Enumeration columns (ones that can only take one value from a predefined list, such as Status):

  =  !=  IN []  NOT_IN []

• For StringSet columns (e.g. LabelNames):

  CONTAINS_ALL []  CONTAINS_ANY []  CONTAINS_NONE []

Conditions using IN, NOT_IN, CONTAINS_ALL, CONTAINS_ANY and CONTAINS_NONE operators look as follows:

 withCondition("ColumnName IN [Value1, Value2]")

Operators are case-sensitive: starts_with won't work.

Columns

All column names are case-sensitive, and so are all values of enumerated columns (such as Status).

Column	Type	Example
Stats
AverageCpc	Double	withCondition("AverageCpc < 1.45")
AverageCpm	Double	withCondition("AverageCpm > 0.48")
AverageCpv	Double	withCondition("AverageCpv < 0.23")
AveragePageviews	Double	withCondition("AveragePageviews > 0")
AveragePosition	Double	withCondition("AveragePosition > 7.5")
BounceRate	Double	withCondition("BounceRate < 0.5")
Clicks	Long	withCondition("Clicks >= 21")
ConversionRate	Double	withCondition("ConversionRate > 0.1")
Conversions	Long	withCondition("Conversions <= 4")
Cost	Double	withCondition("Cost > 4.48"). The value is in the currency of the account.
Ctr	Double	withCondition("Ctr > 0.01"). Note that Ctr is returned in 0..1 range, so 5% Ctr is represented as 0.05.
Impressions	Long	withCondition("Impressions != 0")
Snippet attributes
DevicePreferenceType	Enumeration: MOBILE, ALL	withCondition("DevicePreferenceType = MOBILE"). Use to fetch only mobile-preferred snippets.

If a stats column is used in the condition, date range must be specified via SnippetSelector.forDateRange(String) or SnippetSelector.forDateRange(Object, Object).

Arguments:

Name	Type	Description
condition	String	Condition to add to the selector.

Return values:

Type	Description
AdsApp.SnippetSelector	The selector with the condition applied.

withIds(ids)

Restricts this selector to return only snippets with the given snippet IDs.

 var snippetIds = [12345, 23456, 34567];
 selector = selector.withIds(snippetIds);

The resulting selector can be further refined by applying additional conditions to it. The ID-based condition will then be AND-ed together with all the other conditions, including any other ID-based conditions. So, for instance, the following selector:

 AdsApp.extensions().snippets()
    .withIds([12345, 23456, 34567])
    .withIds([34567, 45678, 56789]);

will only get the snippet with ID 34567, since it would be the only snippet that satisfies both ID conditions.

The selector can only support up to 10,000 IDs. If more than 10,000 IDs are specified, the corresponding get() call will fail with a runtime error.

Arguments:

Name	Type	Description
ids	long[]	Array of snippet IDs.

Return values:

Type	Description
AdsApp.SnippetSelector	The selector restricted to the given IDs.

withLimit(limit)

Specifies limit for the selector to use. For instance, withLimit(50) returns only the first 50 entities.

Arguments:

Name	Type	Description
limit	int	How many entities to return.

Return values:

Type	Description
AdsApp.SnippetSelector	The selector with limit applied.
