Snowflake array match

Table Functions. This topic provides a list of all Snowflake system-defined i. Numeric Functions. Computes the inverse cosine arc cosine of its input; the result is a number in the interval [-pi, pi].

Adds or subtracts a specified number of months to a date or timestamp, preserving the end-of-month information.

Aggregate FunctionsWindow Functions. Uses HyperLogLog to return an approximation of the distinct cardinality of the input i. HLL col1, col2, Returns an approximated value for the desired percentile i. Returns the internal representation of the t-Digest state as a JSON object at the end of aggregation.

Uses Space-Saving to return an approximation of the most frequent values in the input, along with their approximate frequencies. Returns the approximate most frequent values and their estimated frequency for the given Space-Saving state. Semi-structured Data Functions. Returns a compacted array with missing and null values removed, effectively converting sparse arrays into dense arrays.

Returns an array constructed from zero, one, or more inputs; the constructed array omits any NULL input values. Returns True if the specified variant is found in the specified array. Computes the inverse sine arc sine of its argument; the result is a number in the interval [-pi, pi]. Computes the inverse tangent arc tangent of its argument; the result is a number in the interval [-pi, pi]. This table function is used for querying the Automatic Clustering history for given tables within a specified date range.

Information SchemaTable Functions. Returns TRUE when the input expression numeric or string is within the specified lower and upper boundary. Conditional Expression Functions. Bitwise Expression Functions. Shifts the bits for a numeric expression n positions to the left. Shifts the bits for a numeric expression n positions to the right. Computes the Boolean XOR of two numeric expressions i.For instance, We need to find the numerically closest match and its corresponding results from the table.

We need some fixed formula which helps in finding the closest match as to get the required value. Now we will make a formula using the above functions. MATCH function will return the index of the closest match from the range. DONOT use curly braces manually. The above statements can be complicated to understand. Here we have some random date values and a given date value.

Named range used for data D4:D Here we used the named range instead for cell reference array as it's easy to understand. We need to look for the date which is closest to the given date in G6 cell.

Array formula is a formula where an array of values goes from one function result as argument to outer function. As you can see from the above snapshot we obtained the closest matching from the given date in the table. Extract details from the table using the above stated formula.

We need to take a further look into the data provided. Instead of going through each row manually that would be quite boring and increases the risk of making mistakes we need to use a lookup function.

In Excel, we call this the lookup value. Got a different version? No problem, you can still follow the exact same steps. I recommend creating a defined area where I can select the different criteria and type the formula.

Additionally, I hold the left mouse button down on the line between the column names and drag to make them wider, so that the entire content of the cell fits. You might recall that I told you that any lookup function needs to look for a unique piece of information.

Unfortunately, none of the information in the employee database is unique, not even last name or date of birth. However combining last name AND date of birth greatly increases the chances of finding a unique value. So combining last name and date of birth is the smarter choice as this creates a unique identifier in most cases. We, therefore, went ahead and created a unique identifier ourselves by using different criteria, in order to create something unique to look for.

In this case, we are looking for an employee with a last name equivalent to the one we entered in cell J2. Select or enter manually cell J2 as lookup value, then separate with a comma to move on to the lookup array.

And now you see a little drop-down menu that give you the choice between 1, 0 and To be frank, the 1 and -1 options are rarely used, because you almost always want to find an exact match when you are looking for something. The easiest way is to select the entire data range from our employee database and type a comma in the end to move on to the row number. What you enter here tells the INDEX function what column in the employee database you want to return data from. The entire employee database consists of 7 columns A through Gstarting with first name in column A and ending with salary in column G.

So chose what you want the result to be. Now the formula is done and you can finish with a right parenthesis. Whose salary are we actually seeing? In the following we are going to transform a normal formula to an array formula. The first criterion is that the last name must be equal to whatever we type in cell J2.

After this, you enclose the entire criterion with a parenthesis starting before the B:B and ending after the J2.Teachers Pay Teachers is an online marketplace where teachers buy and sell original educational materials.

This example uses RegExp instead of the like function wildcards. It's overloaded so you can use standard RegExp or one with parameters i for case insensitivity in particular.

If you want, you can do a simple modification to return the value of "i", which will be the ordinal position of the first match in the array, or -1 if it leaves the loop not found. Learn more.

The function implicitly anchors a pattern at both ends i.

For more usage notes, see the General Usage Notes for regular expression functions. The Snowflake string parser, which parses literal strings, also treats backslash as an escape character. For example, a backslash is used as part of the sequence of characters that specifies a tab character. Thus to create a string that contains a single backslash, you must specify two backslashes. For example, compare the string in the input statement below with the corresponding string in the output:.

This example shows how to search for a blank followed by a backslash. Note that the single backslash to search for is represented by four backslashes below; for REGEXP to look for a literal backslash, that backslash must be escaped, so you need two backslashes.

The string parser requires that each of those backslashes be escaped, so the expression contains four backslashes to represent the one backslash that the expression is searching for:. Next Previous. Both inputs must be text expressions.Suppose I have the following table:. I would like to count the number of distinct guids in a time span, and for each day in that timespan. I have figured out the last part but still struggling with the first part.

I can't figure out how to flatten the array containing all guids in the entire time span and then use the HyperLogLog function to count the distinct values. My non-functional attempt currently looks like this:. Any chance you provide an extremely simplified sample of data and expected results.

I would expect that 10 or so simple bogus rows will suffice. With that "spec", I am pretty sure that a solid answer will be provided. An example of what I ultimately want in my result set:. The second column contains all the unique guids per date.

And the last column contains all unique guids in the entire result result and not per day. And it is the last column I'm struggling with. Still not fully understanding since you did not provide sample input data. For example, does the "4" refer to the distinct guid count forand the "5" refer to the distinct guid count for ?

If so, does the fact that you have ", Consider the sample table in my original post and pretend that the values in the 'timestamp' column are in unix format number of seconds since What I ultimately want when I issue my query against that table is a result set which contains a single row with 3 columns.

The first column should contain all the dates as an array. The second column should contain the number of unique guid values found for each date. This is again no problem, I can for example issue the following query to get the desired result:. However, I want the third column to contain the number of unique guid values found in the entire result set, and not just per date. And this is where it gets tricky. I have tried being clever by creating a huge string with all the guids in a subquery, then splitting the string up and counting the distinct values using the HLL Did you see the rather comprehensive solution I provided?
