while executing this query i am getting error
UPDATE treedetailsentered
set geom_line=st_geomfromtext('LineString(('||longitude||' '||latitude||','||lon2||' '||lat2||'))', 4326);
error
ERROR: parse error - invalid geometry
HINT: "LineString((7" <-- parse error at position 13 within geometry
********** Error **********
this is how i created column in table for the linestring
ALTER TABLE public.treedetailsentered
ADD COLUMN geom_line geometry(LineString, 4326)
It's hard to tell what the exact problem is without knowing what type longitude, latitude have, but my guess is that you're not forming a proper string.
My advice is to debug this by first creating a proper text via a query that's simpler:
select 'LineString(('||longitude||' '||latitude||','||lon2||' '||lat2||'))'
Depending on what types you have, you might have to do some conversions, like this:
select 'LineString(('||longitude::text||' '||latitude::text||','||lon2::text||' '||lat2::text||'))'
If you already have texts, make sure that the numbers are properly formatted. Floats are expected to have a dot decimal separator for example.
I have added an extra bracket i removed that it worked for me.
UPDATE treedetailsentered set geom_line=ST_GeomFromText('LINESTRING(' || longitude || ' '||latitude||','||lon2||' '||lat2||')', 4326);

I read through snowflake documentation and the web and found only one solution to my problem by https://stackoverflow.com/users/12756381/greg-pavlik which can be found here Snowflake JSON to tabular
This doesn't work on data with Russian attribute names and attribute values. What modifications can be made for this to fit my case?
Here is an example:
create or replace table target_json_table(
v variant
);
INSERT INTO target_json_table SELECT parse_json('{
"at": {
"cf": "NV"
},
"pd": {
"мо": "мо",
"ä": "ä",
"retailerName": "retailer",
"productName":"product"
}
}');
call create_view_over_json('target_json_table', 'V', 'MY_VIEW');
ERROR: Encountered an error while creating the view. SQL compilation error: syntax error line 7 at position 7 unexpected 'ä:'. syntax error line 8 at position 7 unexpected 'мо'.
There was a bug in the original SQL used as a basis for the creation of the stored procedure. I have corrected that. You can get an update on the Github page. The changed section is here:
sql =
`
SELECT DISTINCT '"' || array_to_string(split(f.path, '.'), '"."') || '"' AS path_nAme, -- This generates paths with levels enclosed by double quotes (ex: "path"."to"."element"). It also strips any bracket-enclosed array element references (like "[0]")
DECODE (substr(typeof(f.value),1,1),'A','ARRAY','B','BOOLEAN','I','FLOAT','D','FLOAT','STRING') AS attribute_type, -- This generates column datatypes of ARRAY, BOOLEAN, FLOAT, and STRING only
'"' || array_to_string(split(f.path, '.'), '.') || '"' AS alias_name -- This generates column aliases based on the path
FROM
#~TABLE_NAME~#,
LATERAL FLATTEN(#~COL_NAME~#, RECURSIVE=>true) f
WHERE TYPEOF(f.value) != 'OBJECT'
AND NOT contains(f.path, '[') -- This prevents traversal down into arrays
limit ${ROW_SAMPLE_SIZE}
`;
Previously this SQL simply replaced non-ASCII characters with underscores. The updated SQL will wrap key names in double quotes to create non-ASCII key names.
Be sure that's what you want it to do. Also, the keys are nested. I decided that the best way to handle that is to create column names in the view with dot notation, for example one column name is pd.ä. That will require wrapping the column name with double quotes, such as:
select * from MY_VIEW where "pd.ä" = 'ä';
Final note: The name of your stored procedure is create_view_over_json, however, in the Github project the name is create_view_over_variant. When you update, be sure to call the right procedure.
I've got a table full of WKT (well known text) in a varchar(max) column. This is formatted exactly as geometry. So, for example, one of the values is:
POLYGON ((174.893529167059 -37.0260462162965,174.89351593407 -37.0260221329151,174.893508034056 -37.0260077002766,174.893444415879 -37.0258916500588,174.893416916056 -37.0258414997842,174.893481733297 -37.0258186834198,174.893492016755 -37.0258150663863,174.89349653254 -37.025823316032,174.893512415978 -37.0258522827285,174.893556883897 -37.0259333832477,174.893591032956 -37.0259956661343,174.893604265986 -37.0260197504078,174.893575149738 -37.0260300006258,174.893529167059 -37.0260462162965))
However, I need to convert this varchar(max) field into a geometry field. Unfortunately, SQL Server needs to have some other information in order to do this, so I can't just change the type of the field from varchar(max) to geometry.
I've created a blank geometry column in the same table (MyGeometry) but I'm failing in trying to convert it. Here is my code (where 2193 is the CRS I'm dealing with). WKT is my varchar(max) field and MyGeometry is my new geometry field.
UPDATE MY_TABLE
SET MyGeometry = geometry::STPolyFromText('' + WKT + '', 2193)
EDIT - currently coming back saying the WKT is not valid (System.FormatException 24111 - the input isn't valid).
Which is strange as it matches up perfectly with some other inputs I have in how it's styled.
This will do :
UPDATE MY_TABLE
SET MyGeometry = geometry::STGeomFromText('POLYGON ((174.893529167059 -37.0260462162965,174.89351593407 -37.0260221329151,174.893508034056 -37.0260077002766,174.893444415879 -37.0258916500588,174.893416916056 -37.0258414997842,174.893481733297 -37.0258186834198,174.893492016755 -37.0258150663863,174.89349653254 -37.025823316032,174.893512415978 -37.0258522827285,174.893556883897 -37.0259333832477,174.893591032956 -37.0259956661343,174.893604265986 -37.0260197504078,174.893575149738 -37.0260300006258,174.893529167059 -37.0260462162965))', 0)
You can change that 'POLYGON....' to your VARCHAR(MAX) field.
0 at the end, which is SRID only relevant if you're using Geography.
You can also try :-
UPDATE MY_TABLE SET MyGeometry = GEOMETRY::STGeomFromText('POLYGON ((174.893529167059 -37.0260462162965,174.89351593407 -37.0260221329151,174.893508034056 -37.0260077002766,174.893444415879 -37.0258916500588,174.893416916056 -37.0258414997842,174.893481733297 -37.0258186834198,174.893492016755 -37.0258150663863,174.89349653254 -37.025823316032,174.893512415978 -37.0258522827285,174.893556883897 -37.0259333832477,174.893591032956 -37.0259956661343,174.893604265986 -37.0260197504078,174.893575149738 -37.0260300006258,174.893529167059 -37.0260462162965))',4326);
The value of SRID passed should be 4326 and not 0
You can check the URL below. I found this information in another similar question (older post) so pasting it without any changes
I found solution, SQL Server Spatial Tools
http://sqlspatialtools.codeplex.com/
Followings are the methods solved my problem.
IsValidGeographyFromText(string inputWKT, int srid)
Check if an input WKT can represent a valid geography. This function requires that the WTK coordinate values are longitude/latitude values, in that order and that a valid geography SRID value is supplied. This function will not throw an exception even in edge conditions (i.e. longitude/latitude coordinates are reversed to latitude/longitude).
SqlGeography MakeValidGeographyFromText(string inputWKT, int srid)
Convert an input WKT to a valid geography instance. This function requires that the WKT coordinate values are longitude/latitude values, in that order and that a valid geography SRID value is supplied.
I am trying to run the following PostGIS query:
select ST_distance_spheroid(
ST_GeomFromText('POINT(
(select AsText(location) from test where name="EGMC")
)', 4326),
ST_GeomFromText('POINT(
(select AsText(location) from test where name="EGDY")
)', 4326),
'SPHEROID["WGS_1984",6378137,298.257223563]'
);
but keep getting an error:
ERROR: parse error - invalid geometry
HINT: "POINT(
(s" <-- parse error at position 9 within geometry
I'm happy that I know what the error means, I just don't know how to go about achieving what I want to do. I don't want to manually specify the location, it's stored in the database! I know the name of the place, so I want to get it's location by looking it up. How should I be doing this? Also, it seems a bit unnecessary to convert to a string to convert back, what else can I do?
If I can do this without having to specify variables that would be great.
Thanks.
You are mixing SQL and WKT, which are not the same. Furthermore, you don't need to recreate geometries that already exist. Query the existing geometries instead:
select ST_distance_spheroid(g1.location, g2.location, 'SPHEROID["WGS_1984",6378137,298.257223563]')
from test g1, test g2
where g1.name = "EGMC" and g2.name = "EGDY";

Replace single quote in sql server
So I'm trying to use the following code:
UPDATE TableName
SET FieldName = REPLACE(FieldName, 'SearchFor', 'ReplaceWith');
It works wonderfully for what I need to do, except for the fact that what I need to search for is "valid driver's license". That apostrophe doesn't seem to agree with the code. I tried doing this:
'valid driver''s license'
...but that doesn't seem to work either. I'm getting the following error:
Argument data type text is invalid for argument 1 of replace function.
If anyone has dealt with this before, I would love some help! This would save me so much time, rather than updating each record by hand. -__-

The error tells you exactly what the problem is. FieldName is a column of type text, which doesn't work with the REPLACE function. Try casting the first param as VARCHAR(MAX) first, and it should work. IE:
UPDATE TableName
SET FieldName = REPLACE(CAST(FieldName AS VARCHAR(MAX)), 'SearchFor', 'ReplaceWith');
That's funny. I just ran into this exact thing a few minutes ago. It turns out I had to change this:
UPDATE TableName
SET FieldName = REPLACE(FieldName, 'SearchFor', 'ReplaceWith');
to this:
UPDATE TableName
SET FieldName = REPLACE(cast(FieldName as varchar(5000)), 'SearchFor', 'ReplaceWith');
You must escape the single quote with a slash.
UPDATE TableName
SET FieldName = REPLACE(FieldName, 'Isn\'t', 'Is not');
On the query below I keep getting this error:
Cannot read the next data row for the dataset DataSetProject. (rsErrorReadingNextDataRow)
It appears to be the where clause, if I take it out it seems to work. So I added a cast to the where clause with no luck. Is there something special I need to do in the where clause to get this to work? Just an FYI this is in a report that is pulling an id from the url.
SELECT new_projects.new_projectsId AS ProjectId
, new_projects.new_name AS ProjectName
, new_projects.new_Description AS ProjectDescription
FROM
new_projects
LEFT OUTER JOIN new_projectsteps
ON new_projects.new_projectsId = new_projectsteps.new_ProjectSteps2Id
LEFT OUTER JOIN Task
ON new_projectsteps.new_projectstepsId = Task.RegardingObjectId
WHERE
(new_projects.new_projectsId = cast(#id AS UNIQUEIDENTIFIER))
Thanks!
EDIT:
The id in SQL is a Unique Identifier, the value of #id is being pulled from the querystring(url). So it would look like: &id='BC02ABC0-A6A9-E111-BCAD-32B731EEDD84'
Sorry for the missing info.
I suspect the single quotes are coming through. So either don't have them there by stripping them out before being passed to your parameter or use:
WHERE new_projects.new_projectsId = CONVERT(UNIQUEIDENTIFIER, REPLACE(#id, '''', ''));
If you try a direct comparison when the GUID contains other characters, you should get:
Msg 8169, Level 16, State 2, Line 1 Conversion failed when
converting from a character string to uniqueidentifier.
If this is not what's happening, then don't say "the id in SQL is a Unique Identifier" - show ALL of the code so we can try to reproduce the problem.
